+/* miniz.c 3.0.0 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
+ See "unlicense" statement at the end of this file.
+ Rich Geldreich , last updated Oct. 13, 2013
+ Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt
+
+ Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define
+ MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).
+
+ * Low-level Deflate/Inflate implementation notes:
+
+ Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
+ greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
+ approximately as well as zlib.
+
+ Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
+ coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
+ block large enough to hold the entire file.
+
+ The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
+
+ * zlib-style API notes:
+
+ miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in
+ zlib replacement in many apps:
+ The z_stream struct, optional memory allocation callbacks
+ deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
+ inflateInit/inflateInit2/inflate/inflateReset/inflateEnd
+ compress, compress2, compressBound, uncompress
+ CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines.
+ Supports raw deflate streams or standard zlib streams with adler-32 checking.
+
+ Limitations:
+ The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries.
+ I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but
+ there are no guarantees that miniz.c pulls this off perfectly.
+
+ * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by
+ Alex Evans. Supports 1-4 bytes/pixel images.
+
+ * ZIP archive API notes:
+
+ The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to
+ get the job done with minimal fuss. There are simple API's to retrieve file information, read files from
+ existing archives, create new archives, append new files to existing archives, or clone archive data from
+ one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h),
+ or you can specify custom file read/write callbacks.
+
+ - Archive reading: Just call this function to read a single file from a disk archive:
+
+ void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name,
+ size_t *pSize, mz_uint zip_flags);
+
+ For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central
+ directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files.
+
+ - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file:
+
+ int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags);
+
+ The locate operation can optionally check file comments too, which (as one example) can be used to identify
+ multiple versions of the same file in an archive. This function uses a simple linear search through the central
+ directory, so it's not very fast.
+
+ Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and
+ retrieve detailed info on each file by calling mz_zip_reader_file_stat().
+
+ - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data
+ to disk and builds an exact image of the central directory in memory. The central directory image is written
+ all at once at the end of the archive file when the archive is finalized.
+
+ The archive writer can optionally align each file's local header and file data to any power of 2 alignment,
+ which can be useful when the archive will be read from optical media. Also, the writer supports placing
+ arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still
+ readable by any ZIP tool.
+
+ - Archive appending: The simple way to add a single file to an archive is to call this function:
+
+ mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name,
+ const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags);
+
+ The archive will be created if it doesn't already exist, otherwise it'll be appended to.
+ Note the appending is done in-place and is not an atomic operation, so if something goes wrong
+ during the operation it's possible the archive could be left without a central directory (although the local
+ file headers and file data will be fine, so the archive will be recoverable).
+
+ For more complex archive modification scenarios:
+ 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to
+ preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the
+ compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and
+ you're done. This is safe but requires a bunch of temporary disk space or heap memory.
+
+ 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(),
+ append new files as needed, then finalize the archive which will write an updated central directory to the
+ original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a
+ possibility that the archive's central directory could be lost with this method if anything goes wrong, though.
+
+ - ZIP archive support limitations:
+ No spanning support. Extraction functions can only handle unencrypted, stored or deflated files.
+ Requires streams capable of seeking.
+
+ * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the
+ below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it.
+
+ * Important: For best perf. be sure to customize the below macros for your target platform:
+ #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
+ #define MINIZ_LITTLE_ENDIAN 1
+ #define MINIZ_HAS_64BIT_REGISTERS 1
+
+ * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz
+ uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files
+ (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).

-// Command Line
-//
-// The command line functions below are just simple iteration functions. This command line system is good for
-// simple command lines, but probably not the best for programs requiring complex command line work.
-//
-// For argv style command lines, parse_cmdline() will run without any heap allocations. With a Win32 style
-// command line there will be one malloc() per call fo parse_cmdline(). This is the only function that will do
-// a malloc().
-//
-// Below is an example:
-//
-// dr_cmdline cmdline;
-// if (dr_init_cmdline(&cmdline, argc, argv)) {
-// dr_parse_cmdline(&cmdline, my_cmdline_handler, pMyUserData);
-// }
-//
-// void my_cmdline_handler(const char* key, const char* value, void* pUserData)
-// {
-// // Do something...
-// }
-//
-//
-// When parsing the command line, the first iteration will be the program path and the key will be "[path]".
-//
-// For segments such as "-abcd", the callback will be called for "a", "b", "c", "d" individually, with the
-// value set to NULL.
-//
-// For segments such as "--server", the callback will be called for "server", with the value set to NULL.
-//
-// For segments such as "-f file.txt", the callback will be called with the key set to "f" and the value set
-// to "file.txt".
-//
-// For segments such as "-f file1.txt file2.txt", the callback will be called twice, once for file1.txt and
-// again for file2.txt, with with the key set to "f" in both cases.
-//
-// For segments where there is no leading key, the values will be posted as annonymous (key set to NULL). An example
-// is "my_program.exe file1.txt file2.txt", in which case the first iteration will be the program path, the second iteration
-// will be "file1.txt", with the key set to NULL. The third iteration will be "file2.txt" with the key set to NULL.
-//
-// For segments such as "-abcd file.txt", "a", "b", "c", "d" will be sent with NULL values, and "file.txt" will be
-// posted with a NULL key.

-// Public Domain. See "unlicense" statement at the end of this file.
-
-// ABOUT
-//
-// dr_2d is a simple library for drawing simple 2D graphics.
-//
-//
-//
-// USAGE
-//
-// This is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_2D_IMPLEMENTATION
-// #include "dr_2d.h"
-//
-// You can then #include dr_2d.h in other parts of the program as you would with any other header file.
-//
-//
-//
-// QUICK NOTES
-//
-// - Drawing must be done inside a dr2d_begin_draw() and dr2d_end_draw() pair. Rationale: 1) required for compatibility
-// with GDI's BeginPaint() and EndPaint() APIs; 2) gives implementations opportunity to save and restore state, such as
-// OpenGL state and whatnot.
-// - This library is not thread safe.
-//
-//
-//
-// OPTIONS
-//
-// #define DR2D_NO_GDI
-// Excludes the GDI back-end.
-//
-// #define DR2D_NO_CAIRO
-// Excludes the Cairo back-end.
-//
-//
-//
-// TODO
-// - Document resource management.

-// Audio playback, recording and mixing. Public domain. See "unlicense" statement at the end of this file.
-// dr_audio - v0.0 (unversioned) - Release Date TBD
-//
-// David Reid - mackron@gmail.com
-
-// !!!!! THIS IS WORK IN PROGRESS !!!!!
-
-// USAGE
-//
-// dr_audio is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_AUDIO_IMPLEMENTATION
-// #include "dr_audio.h"
-//
-// You can then #include this file in other parts of the program as you would with any other header file.
-//
-// dr_audio supports loading and decoding of WAV, FLAC and Vorbis streams via dr_wav, dr_flac and stb_vorbis respectively. To enable
-// these all you need to do is #include "dr_audio.h" _after_ #include "dr_wav.h", #include "dr_flac.h" and #include "stb_vorbis.c" in
-// the implementation file, like so:
-//
-// #define DR_WAV_IMPLEMENTATION
-// #include "dr_wav.h"
-//
-// #define DR_FLAC_IMPLEMENTATION
-// #include "dr_flac.h"
-//
-// #define STB_VORBIS_IMPLEMENTATION
-// #include "stb_vorbis.c"
-//
-// #define DR_AUDIO_IMPLEMENTATION
-// #include "dr_audio.h"
-//
-// dr_wav, dr_flac and stb_vorbis are entirely optional, and dr_audio will automatically detect the ones that are available without
-// any additional intervention on your part.
-//
-//
-// dr_audio has a layered API with different levels of flexibility vs simplicity. An example of the high level API follows:
-//
-// dra_device* pDevice;
-// dra_result result = dra_device_create(NULL, dra_device_type_playback, &pDevice);
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// dra_voice* pVoice;
-// result = dra_voice_create_from_file(pDevice, "my_song.flac", &pVoice);
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// dra_voice_play(pVoice, DR_FALSE);
-//
-// ...
-//
-// dra_voice_delete(pVoice);
-// dra_device_delete(pDevice);
-//
-//
-// An example of the low level API:
-//
-// dra_context context;
-// dra_result result = dra_context_init(&context); // Initializes the backend (DirectSound/ALSA)
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// unsigned int deviceID = 0; // Default device
-// unsigned int channels = 2; // Stereo
-// unsigned int sampleRate = 48000;
-// unsigned int latencyInMilliseconds = 0; // 0 will default to DR_AUDIO_DEFAULT_LATENCY.
-// dra_device device;
-// result = dra_device_init_ex(&context, dra_device_type_playback, deviceID, channels, sampleRate, latencyInMilliseconds, &device);
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// dra_voice* pVoice;
-// dra_result result = dra_voice_create(pDevice, dra_format_f32, channels, sampleRate, voiceBufferSizeInBytes, pVoiceSampleData, &pVoice);
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// ...
-//
-// // Sometime later you may need to update the data inside the voice's internal buffer... It's your job to handle
-// // synchronization - have fun! Hint: use playback events at fixed locations to know when a region of the buffer
-// // is available for updating.
-// float* pVoiceData = (float*)dra_voice_get_buffer_ptr_by_sample(pVoice, sampleOffset);
-// if (pVoiceData == NULL) {
-// return -1;
-// }
-//
-// memcpy(pVoiceData, pNewVoiceData, sizeof(float) * samplesToCopy);
-//
-// ...
-//
-// dra_voice_delete(pVoice);
-// dra_device_uninit(pDevice);
-// dra_context_uninit(pContext);
-//
-// In the above example the voice and device are configured to use the same number of channels and sample rate, however they are
-// allowed to differ, in which case dr_audio will automatically convert the data. Note that sample rate conversion is currently
-// very low quality.
-//
-// To handle streaming buffers, you can attach a callback that's fired when a voice's playback position reaches a certain point.
-// Usually you would set this to the middle and end of the buffer, filling the previous half with new data. Use the
-// dra_voice_add_playback_event() API for this.
-//
-// The playback position of a voice can be retrieved and set with dra_voice_get_playback_position() and dra_voice_set_playback_position()
-// respctively. The playback is specified in samples. dra_voice_get_playback_position() will always return a value which is a multiple
-// of the channel count. dra_voice_set_playback_position() will round the specified sample index to a multiple of the channel count.
-//
-//
-// dr_audio has support for submixing which basically allows you to control volume (and in the future, effects) for groups of sounds
-// which would typically be organized into categories. An abvious example would be in games where you may want to have separate volume
-// controls for music, voices, special effects, etc. To do submixing, all you need to do is create a mixer. There is a master mixer
-// associated with every device, and all newly created mixers are a child of the master mixer, by default:
-//
-// dra_mixer* pMusicMixer;
-// dra_result result = dra_mixer_create(pDevice, &pMusicMixer);
-// if (result != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// // At this point pMusicMixer is a child of the device's master mixer. To change the hierarchy, just do something like this:
-// dra_mixer_attach_submixer(pSomeOtherMixer, pMusicMixer);
-//
-// // A voice is attached to the master mixer by default, but you can attach it to a different mixer like this:
-// dra_mixer_attach_voice(pMusicMixer, pMyMusicVoice);
-//
-// // Control the volume of the mixer...
-// dra_mixer_set_volume(pMusicMixer, 0.5f); // <-- The volume is linear, so this is half volume.
-//
-//
-//
-// dr_audio includes an abstraction for audio decoding. Built-in support is included for WAV, FLAC and Vorbis streams:
-//
-// dra_decoder decoder;
-// if (dra_decoder_open_file(&decoder, filePath) != DRA_RESULT_SUCCESS) {
-// return -1;
-// }
-//
-// dr_uint64 samplesRead = dra_decoder_read_f32(&decoder, samplesToRead, pSamples);
-// update_my_voice_data(pVoice, pSamples, samplesRead);
-//
-// dra_decoder_close(&decoder);
-//
-// Decoders can be opened/initialized from files, a block of memory, or application-defined callbacks.

-// - Add support for the push API in stb_vorbis.
-
-// DEVELOPMENT NOTES AND BRAINSTORMING
-//
-// This is just random brainstorming and is likely very out of date and often just outright incorrect.
-//
-//
-// Latency
-//
-// When a device is created it'll create a "hardware buffer" which is basically the buffer that the hardware
-// device will read from when it needs to play audio. The hardware buffer is divided into two halves. As the
-// buffer plays, it moves the playback pointer forward through the buffer and loops. When it hits the half
-// way point it notifies the application that it needs more data to continue playing. Once one half starts
-// playing the data within it is committed and cannot be changed. The size of each half determines the latency
-// of the device.
-//
-// It sounds tempting to set this to something small like 1ms, but making it too small will
-// increase the chance that the CPU won't be able to keep filling it with fresh data. In addition it will
-// incrase overall CPU usage because operating system's scheduler will need to wake up the thread more often.
-// Increasing the latency will increase memory usage and make playback of new sound sources take longer to
-// begin playing. For example, if the latency was set to something like 1 second, a sound effect in a game
-// may take up to a whole second to start playing. A balance needs to be made when setting the latency, and
-// it can be configured when the device is created.
-//
-// (mention the fragments system to help avoiding the CPU running out of time to fill new audio data)
-//
-//
-// Mixing
-//
-// Mixing is done via dra_mixer objects. Buffers can be attached to a mixer, but not more than one at a time.
-// By default buffers are attached to a master mixer. Effects like volume can be applied on a per-buffer and
-// per-mixer basis.
-//
-// Mixers can be chained together in a hierarchial manner. Child mixers will be mixed first with the result
-// then passed on to higher level mixing. The master mixer is always the top level mixer.
-//
-// An obvious use case for mixers in games is to have separate volume controls for different categories of
-// sounds, such as music, voices and sounds effects. Another example may be in music production where you may
-// want to have separate mixers for vocal tracks, percussion tracks, etc.
-//
-// A mixer can be thought of as a complex buffer - it can be played/stopped/paused and have effects such as
-// volume apllied to it. All of this affects all attached buffers and sub-mixers. You can, for example, pause
-// every buffer attached to the mixer by simply pausing the mixer. This is an efficient and easy way to pause
-// a group of audio buffers at the same time, such as when the user hits the pause button in a game.
-//
-// Every device includes a master mixer which is the one that buffers are automatically attached to. This one
-// is intentionally hidden from the public facing API in order to keep it simpler. For basic audio playback
-// using the master mixer will work just fine, however for more complex sound interactions you'll want to use
-// your own mixers. Mixers, like buffers, are attached to the master mixer by default
-//
-//
-// Thread Safety
-//
-// Everything in dr_audio should be thread-safe.
-//
-// Backends are implemented as if they are always run from a single thread. It's up to the cross-platform
-// section to ensure thread-safety. This is an important property because if each backend is responsible for
-// their own thread safety it increases the likelyhood of subtle backend-specific bugs.
-//
-// Every device has their own thread for asynchronous playback. This thread is created when the device is
-// created, and deleted when the device is deleted.
-//
-// (Note edge cases when thread-safety may be an issue)

-//
-// QUICK NOTES
-//
-// If you've stumbled across this library, be aware that this is very, very early in development. A lot of APIs
-// are very temporary, in particular the effects API which at the moment are tied very closely to DirectSound.
-//
-// Currently, the only backend available is DirectSound while I figure out the API.
-//
-// General
-// - This library is NOT thread safe. Functions can be called from any thread, but it is up to the host application
-// to do synchronization.
-// - This library is only concerned with playback and recording of raw audio data. It does not load audio files
-// such as WAV, OGG and MP3.
-// - Before you can create an output (playback) or input (recording) device you need to first create a context.
-// - Each backend (DirectSound, ALSA, etc.) has it's own context. Using draudio_create_context() will find
-// a backend implementation based on the platform dr_audio has been compiled for.
-// - A context for a specific backend can be created as well. For example, draudio_create_context_dsound() will
-// create a context which uses DirectSound as it's backend.
-// - Currently, devices are enumerated once when the context is created. Thus, when a device is plugged in or
-// unplugged it will not be detected by dr_audio and the context will need to be deleted and re-created.
-// - Currently, dr_audio will only consider the first DRAUDIO_MAX_DEVICE_COUNT output and input devices, which
-// is currently set to 16 and should be plenty for the vast majority of cases. Feel free to increase (or decrease)
-// this number to suit your own requirements.
-//
-// Events
-// - Events are handled via callbacks. The different types of events include stop, pause, play and markers.
-// - The Stop event is fired when an output buffer is stopped, either from finishing it's playback or if it was
-// stopped manually.
-// - The Pause event is fired when the output buffer is paused.
-// - The Play event is fired when the output buffer begins being played from either a stopped or paused state.
-// - A Marker event is fired when the playback position of an output buffer reaches a certain point within the
-// buffer. This is useful for streaming audio data because it can tell you when a particular section of the
-// buffer can be filled with new data.
-// - Due to the inherent multi-threaded nature of audio playback, events can be fired from any thread. It is up
-// to the application to ensure events are handled safely.
-// - Currently, the maximum number of markers is set by DRAUDIO_MAX_MARKER_COUNT which is set to 4 by default. This
-// can be increased, however doing so increases memory usage for each sound buffer.
-//
-// Performance Considerations
-// - Creating and deleting buffers should be considered an expensive operation because there is quite a bit of thread
-// management being performed under the hood. Prefer caching sound buffers.
-//
-
-//
-// OPTIONS
-//
-// #define DRAUDIO_NO_DIRECTSOUND
-// Disables support for the DirectSound backend. Note that at the moment this is the only backend available for
-// Windows platforms, so you will likely not want to set this. DirectSound will only be compiled on Win32 builds.
-//
-
-//
-// TODO
-//
-// - DirectSound: Consider using Win32 critical sections instead of events where possible.
-// - DirectSound: Remove the semaphore and replace with an auto-reset event.
-// - Implement a better error handling API.
-// - Implement effects
-// - Implement velocity
-// - Implement cones
-// - Implement attenuation min/max distances

-// The DirectSound backend is mostly simple, except for event handling. Events
-// are achieved through the use of Win32 event objects and waiting on them to
-// be put into a signaled state by DirectSound. Due to this mechanic we need to
-// create a worker thread that waits on each event.
-//
-// The worker thread waits on three general types of events. The first is an
-// event that is signaled when the thread needs to be terminated. The second
-// is an event that is signaled when a new set of events need to be waited on.
-// The third is a set of events that correspond to an output buffer event (such
-// as stop, pause, play and marker events.)

-// Public Domain. See "unlicense" statement at the end of this file.
-//
-// Includes code from miniz.c which can be found here: https://github.com/richgel999/miniz
-
-// NOTE: dr_fs is very early in development and should be considered unstable. Expect many APIs to change.
-
-// ABOUT
-//
-// dr_fs is a simple library which abstracts file IO to allow one to open files from both the native file
-// system and archive/package files such as Zip files using a common API.
-//
-// This file includes code from miniz.c which has been stripped down to include only what's needed to support
-// Zip files at basic level. Every public API has been namespaced with "drfs_" to avoid naming conflicts.
-//
-// Some noteworthy features:
-// - Supports verbose absolute paths to avoid ambiguity. For example you can specify a path
-// such as "my/package.zip/file.txt"
-// - Supports shortened, transparent paths by automatically scanning for supported archives. The
-// path "my/package.zip/file.txt" can be shortened to "my/file.txt", for example. This does not
-// work for absolute paths, however. See notes below.
-// - Fully recursive. A path such as "pack1.zip/pack2.zip/file.txt" should work just fine.
-// - Easily supports custom package formats without the need to modify the original source code.
-// Look at drfs_register_archive_backend() and the implementation of Zip archives for an
-// example.
-// - No dependencies except for the C standard library.
-//
-// Limitations:
-// - When a file contained within a Zip file is opened, the entire uncompressed data is loaded
-// onto the heap. Keep this in mind when working with large files.
-// - Zip, PAK and Wavefront MTL archives are read-only at the moment.
-// - dr_fs is not fully thread-safe. See notes below.
-// - Asynchronous IO is not supported.
-//
-//
-//
-// USAGE
-//
-// This is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_FS_IMPLEMENTATION
-// #include "dr_fs.h"
-//
-// You can then #include dr_fs.h in other parts of the program as you would with any other header file.
-//
-// Example:
-// // Create a context.
-// drfs_context* pVFS = drfs_create_context();
-// if (pVFS == NULL) {
-// // There was an error creating the context.
-// }
-//
-// // Add your base directories for loading from relative paths. If you do not specify at
-// // least one base directory you will need to load from absolute paths.
-// drfs_add_base_directory(pVFS, "C:/Users/Admin");
-// drfs_add_base_directory(pVFS, "C:/My/Folder");
-//
-// ...
-//
-// // Open a file. A relative path was specified which means it will first check it against
-// // "C:/Users/Admin". If it can't be found it will then check against "C:/My/Folder".
-// drfs_file* pFile;
-// drfs_result result = drfs_open(pVFS, "my/file.txt", DRFS_READ, &pFile);
-// if (result != drfs_success) {
-// // There was an error loading the file. It probably doesn't exist.
-// }
-//
-// result = drfs_read(pFile, buffer, bufferSize, NULL);
-// if (result != drfs_success) {
-// // There was an error reading the file.
-// }
-//
-// drfs_close(pFile);
-//
-// ...
-//
-// // Shutdown.
-// drfs_delete_context(pVFS);
-//
-//
-//
-// OPTIONS
-//
-// To use these options, just place the appropriate #define's in the .c file before including this file.
-//
-// #define DR_FS_NO_ZIP
-// Disable built-in support for Zip files.
-//
-// #define DR_FS_NO_PAK
-// Disable support for Quake 2 PAK files.
-//
-// #define DR_FS_NO_MTL
-// Disable support for Wavefront MTL files.
-//
-//
-//
-// THREAD SAFETY
-//
-// dr_fs is not fully thread safe. Known unsafe functionality includes:
-// - Opening a file while adding or removing base directories and backends
-// - Closing a file while doing anything on that file object
-// - drfs_open() will malloc() the drfs_file object, and drfs_close() will free() it with no garbage collection
-// nor reference counting.
-//
-// The issues mentioned above should not be an issue for the vast majority of cases. Base directories and backends
-// will typically be registered once during initialization when the context is created, and it's unlikely an
-// application will want to close a file while simultaneously trying to use it on another thread without doing it's
-// own synchronization anyway.
-//
-// Thread-safety has not been completely ignored either. It is possible to read, write and seek on multiple threads.
-// In this case it is a simple matter of first-in first-served. Also, APIs are in place to allow an application to
-// do it's own synchronization. An application can use drfs_lock() and drfs_unlock() to lock and unlock a file using
-// simple mutal exclusion. Inside the lock/unlock pair the application can then use the "_nolock" variation of the
-// relevant APIs:
-// - drfs_read_nolock()
-// - drfs_write_nolock()
-// - drfs_seek_nolock()
-// - drfs_tell_nolock()
-// - drfs_size_nolock()
-//
-// Opening two files that share the same archive should work fine across multiple threads. For example, if you have
-// an archive called MyArchive.zip and then open two files within that archive, you can do work with each of those
-// files independently on separate threads. This functionality depends on the implementation of the relevant backend,
-// however.
-//
-// When implementing a backend, it is important to keep synchronization in mind when reading data from the host
-// archive file. To help with this, use the drfs_lock() and drfs_unlock() combined with the "_nolock" variations
-// of the APIs listed above.
-//
-//
-//
-// QUICK NOTES
-//
-// - The library works by using the notion of an "archive" to create an abstraction around the file system.
-// - Conceptually, and archive is just a grouping of files and folders. An archive can be a directory on the native
-// file system or an actual archive file such as a .zip file.
-// - When iterating over files and folder, the order is undefined. Do not assume alphabetical.
-// - When a path includes the name of the package file, such as "my/package.zip/file.txt" (note how the .zip file is
-// included in the path), it is referred to as a verbose path.
-// - When specifying an absolute path, it is assumed to be verbose. When specifying a relative path, it does not need
-// to be verbose, in which case the library will try to search for it. A path such as "my/package.zip/file.txt" is
-// equivalent to "my/file.txt".
-// - Archive backends are selected based on their extension.
-// - Archive backends cannot currently share the same extension. For example, many package file formats use the .pak
-// extension, however only one backend can use that .pak extension.
-// - For safety, if you want to overwrite a file you must explicitly call drfs_open() with the DRFS_TRUNCATE flag.
-// - Platforms other than Windows do not use buffering. That is, they use read() and write() instead of fread() and
-// fwrite().
-// - On Linux platforms, if you are having issues with opening files larger than 2GB, make sure this file is the first
-// file included in the .c file. This ensures the _LARGEFILE64_SOURCE macro is defined before any other header file
-// as required for the use of 64-bit variants of the POSIX APIs.
-// - Base paths must be absolute and verbose.
-//
-//
-//
-// TODO:
-//
-// - Test result code consistency.
-// - Document performance issues.
-// - Consider making it so persistent constant strings (such as base paths) use dynamically allocated strings rather
-// than fixed sized arrays of DRFS_MAX_PATH.
-// - Replace the miniz reading functionality with a custom one:
-// - There is a sort-of-bug where miniz does not correctly enumerate directories in a zip file that was created with
-// the "Send to -> Compressed (zipped) folder" functionality in Windows Explorer. This is more of a thing with
-// Windows Explorer more than anything, but it'd be nice if it would Just Work.
-// - miniz does not support streamed reading yet. Instead, one must decompress the entire file onto the heap which
-// is a bit untidy and doesn't work well with very large files.
-// - ZIP64 is not supported.

-// Public Domain. See "unlicense" statement at the end of this file.
-
-// ABOUT
-//
-// dr_fsw is a simple library for watching for changes to the file system. This is not a full-featured library
-// and is only intended for basic use cases.
-//
-// Limitations:
-// - Only Windows is supported at the moment.
-//
-//
-//
-// USAGE
-//
-// This is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_FSW_IMPLEMENTATION
-// #include "dr_fsw.h"
-//
-// You can then #include this file in other parts of the program as you would with any other header file.
-//
-// Example:
-// // Startup.
-// drfsw_context* context = drfsw_create_context();
-// if (context == NULL)
-// {
-// // There was an error creating the context...
-// }
-//
-// drfsw_add_directory(context, "C:/My/Folder");
-// drfsw_add_directory(context, "C:/My/Other/Folder");
-//
-// ...
-//
-// // Meanwhile, in another thread...
-// void MyOtherThreadEntryProc()
-// {
-// drfsw_event e;
-// while (isMyApplicationStillAlive && drfsw_next_event(context, &e))
-// {
-// switch (e.type)
-// {
-// case drfsw_event_type_created: OnFileCreated(e.absolutePath); break;
-// case drfsw_event_type_deleted: OnFileDeleted(e.absolutePath); break;
-// case drfsw_event_type_renamed: OnFileRenamed(e.absolutePath, e.absolutePathNew); break;
-// case drfsw_event_type_updated: OnFileUpdated(e.absolutePath); break;
-// default: break;
-// }
-// }
-// }
-//
-// ...
-//
-// // Shutdown
-// drfsw_context* contextOld = context;
-// context = NULL;
-// drfsw_delete_context(contextOld);
-//
-// Directories are watched recursively, so try to avoid using this on high level directories
-// like "C:\". Also avoid watching a directory that is a descendant of another directory that's
-// already being watched.
-//
-// It does not matter whether or not paths are specified with forward or back slashes; the
-// library will normalize all of that internally depending on the platform. Note, however,
-// that events always report their paths with forward slashes.
-//
-// You don't need to wait for events on a separate thread, however drfsw_next_event() is
-// a blocking call, so it's usually best to do so. Alternatively, you can use
-// drfsw_peek_event() which is the same, except non-blocking. Avoid using both
-// drfsw_next_event() and drfsw_peek_event() at the same time because both will remove
-// the event from the internal queue so it likely won't work the way you expect.
-//
-// The shutdown sequence is a bit strange, but since another thread is accessing that pointer,
-// you should set any shared pointers to null before calling drfsw_delete_context(). That way,
-// the next call to drfsw_next_event() will pass in a null pointer which will cause it to
-// immediately return with zero and thus break the loop and terminate the thread. It is up to
-// the application to ensure the pointer passed to drfsw_next_event() is valid. Deleting a context
-// will cause a waiting call to drfsw_next_event() to return 0, however there is a chance that the
-// context is deleted before drfsw_next_event() has entered into it's wait state. It's up to the
-// application to make sure the context remains valid.
-//
-//
-//
-// QUICK NOTES
-// - Files that are not on the machine's local file system will not be detected (such as files on a network drive).
-// - In some cases, renaming files won't be detected. Instead it may be implemented as a delete/create pair.
-//
-// - Win32: Every directory that is watched becomes "in use" by the operating system. It is still possible
-// to modify the files and folders inside the watched directory, however.
-// - Win32: There is a known issue with the ReadDirectoryChangesW() watch technique (which is used internally)
-// where some events won't get processed if a large number of files change in a short period of time.

-// NOTES:
-//
-// Win32 and ReadDirectoryChangesW
-//
-// Here is how watching for changes via the ReadDirectoryChangesW() works:
-// 1) You create a handle to the directory with CreateFile()
-// 2) You pass this handle to ReadDirectoryChangesW(), including a pointer to a function that is called when changes to the directory are made.
-// 3) From the aforementioned callback, ReadDirectoryChangesW() needs to be called again
-//
-// There are, however, a lot of details that need to be handled correctly in order for this to work
-//
-// First of all, the callback passed to ReadDirectoryChangesW() will not be called unless the calling thread is in an alertable state. A thread
-// is put into an alertable state with WaitForMultipleObjectsEx() (the Ex version is important since it has an extra parameter that lets you
-// put the thread into an alertable state). Using this blocks the thread which means you need to create a worker thread in the background.

-
-// QUICK NOTES
-//
-// General
-// - dr_gui is a low-level GUI system that works on generic objects referred to as "elements".
-// - An element is the most basic unit in dr_gui. It contains basic information about it's layout and hierarchy.
-// - Elements can be used as the building blocks for more complex controls such as list boxes and scrollbars.
-// - The layout of elements use floats instead of integers. The rationale for this is that it makes it easier to do certain
-// layout arithmetic. For example, if you want to evenly distribute 3 elements across a fixed area, the integer based
-// arithmetic can cause rounding errors which cause the elements to not sit flush against the area. By using float-based
-// arithmetic we can avoid that particular issue.
-//
-// Hierarchy
-// - An element can have a parent and any number of children. If an element does not have a parent, it is referred to as the
-// top-level element.
-// - When an element is deleted, it's children will be deleted as well.
-// - Top-level elements do not have siblings.
-//
-// Event Handling
-// - The application must notify dr_gui of application-generated events such as key strokes and mouse movements. These are
-// referred to as inbound events. An event that is generated by dr_gui are referred to as outbound events.
-// - Inbound events are used to generate outbound events. For example, a mouse-move inbound event will generate an outbound
-// mouse-move event, and perhaps a mouse leave/enter pair.
-// - Outbound events are posted and handled immediately. A call to drgui_post_inbound_event() will not return until all of
-// the outbound events it generates have been handled.
-// - Inbound events are not thread safe, however an application is free to post an inbound event from any thread so long as
-// it does it's own synchronization.
-// - Inbound events will typically specify the relevant top-level element and let dr_gui do the relevant processing required
-// to generate the appropriate outbound events. For example, the mouse-move event will be specified with respect to the top-
-// level element, but dr_gui will determine the exact child element that the mouse moved on and thus should receive the
-// relevant outbound mouse-move event.
-// - There are some special events that are handled differently to normal events. The best example is the paint events. The
-// paint event is only called from drgui_draw().
-// - Key press/release events are only ever posted to the element that has the keyboard capture/focus which is set with
-// drgui_capture_keyboard(). Thus, when posting an inbound key event, a top-level element is not required when posting
-// those events. The relevant context is still required, however.
-//
-// Global Outbound Event Handling
-// - At times dr_gui will need to notify the host application in order for certain functionality to work properly. For example.
-// when the mouse is captured it won't work 100% correct unless the host application has a chance to capture the mouse against
-// the container window. Because dr_gui has no notion of a window system it relies on the host application to handle this
-// properly.
-// - A global outbound event handler should be implemented for each of the following events:
-// - on_dirty: Called when a region of an element is marked as dirty and needs to be redrawn. The application will want to
-// invalidate the container window to trigger an operating system redraw. Set this with drgui_set_global_on_dirty().
-// - on_capture_mouse: Called when the mouse is captured and gives the application the opportunity to capture the mouse against
-// the container window at the operating system level. Set with drgui_set_global_on_capture_mouse().
-// - on_release_mouse: Called when the mouse is released. The opposite of on_capture_mouse.
-// - on_capture_keyboard: Called when an element is given the keyboard focus and gives the application the opportunity to
-// apply the keyboard focus to the container window. Set with drgui_set_global_on_capture_keyboard().
-// - on_release_keyboard: Called when an element loses the keyboard focus. The opposite of on_capture_keyboard.
-// - on_change_cursor: Called when the current cursor needs to be changed as a result of the mouse moving over a new element.
-//
-// Layout
-// - An element's data structure does not store it's relative position but instead stores it's absolute position. The rationale
-// for this is that storing it as relative complicates absolute positioning calculations because it would need to do a recursive
-// traversal of the element's ancestors.
-// - Child elements can be scaled by setting an element's inner scale. The inner scale does not scale the element itself - only
-// it's children.
-// - When an element is drawn, everything is scaled by it's inner scale. For example, if the inner scale is 2x and a 100x100 quad
-// is drawn, the quad will be scaled to 200x200. An exception to this rule is fonts, which are never scaled. This 0s because
-// text is always drawn based on the size of the font.
-// - Applications should only need to work on unscaled coordinates. That is, an application should never need to worry about
-// manual scaling, except for fonts. When positioning and sizing child elements, they should be done based on unscaled
-// coordinates.
-// - Use the inner scale system for DPI awareness.
-// - The inner scale is applied recursively. That is, if a top level element has it's inner scale set to 2x and one of it's
-// children has an inner scale of 2x, the actual inner scale of the child element will be 4x.
-//
-//
-// Drawing/Painting
-// - Drawing is one of the more complex parts of the GUI because it can be a bit unintuitive regarding exactly when an element
-// is drawn and when a drawing function is allowed to be called.
-// - To draw an element, call drgui_draw(). This takes a pointer to the element to draw and the rectangle region that should
-// be redrawn. Any children that fall inside the specified rectangle region will be redrawn as well. You do not want to call
-// drgui_draw() on a parent element and then again on it's children because dr_gui will do that automatically.
-// - drgui_draw() does not draw anything directly, but rather calls painting callback routines which is where the actual
-// drawing takes place.
-// - Sometimes an application will need to be told when a region of an element is dirty and needs redrawing. An example is
-// event-driven, non real-time applications such as normal desktop applications. To mark an element as dirty, you call the
-// drgui_dirty() function which takes the element that is dirty, and the rectangle region that needs to be redrawn. This
-// does not redraw the element immediately, but instead posts an on_dirty event for the application. Marking regions as dirty
-// is not strictly required, but you should prefer it for event-driven applications that require painting operations to be
-// performed at specific times (such as inside Win32's WM_PAINT messages).
-// - Some operations will cause a region of an element to become dirty - such as when it is resized. dr_gui will
-// automatically mark the relevant regions as dirty which in turn will cause a paint message to be posted. If this is not
-// required, it can be disabled with drgui_disable_auto_dirty(). You may want to disable automatic dirtying if you are
-// running a real-time application like a game which would redraw the entire GUI every frame anyway and thus not require
-// handling of the paint message.
-// - Real-time application guidelines (games, etc.):
-// - drgui_disable_auto_dirty()
-// - drgui_draw(pTopLevelElement, 0, 0, viewportWidth, viewportHeight) at the end of every frame after your main loop.
-//
-
-
-//
-// OPTIONS
-//
-// #define DRGUI_NO_DR_2D
-// Disable dr_2d integration. Disabling dr_2d will require you to implement your own drawing callbacks.
-//
-// #define DRGUI_NO_TEXT_EDITING
-// Disables the text box control and text engine.
-
-
-//
-// EXAMPLES
-//
-// Basic Drawing:
-//
-// drgui_draw(pTopLevelElement, 0, 0, drgui_get_width(pTopLevelElement), drgui_get_height(pTopLevelElement));
-//
-// -------------------------
-//
-// Event-Driven Drawing (Win32):
-//
-// void my_global_on_dirty_win32(drgui_element* pElement, drgui_rect relativeRect) {
-// drgui_rect absoluteRect = relativeRect;
-// drgui_make_rect_absolute(pElement, &absoluteRect);
-//
-// RECT rect;
-// rect.left = absoluteRect.left;
-// rect.top = absoluteRect.top;
-// rect.right = absoluteRect.right;
-// rect.height = absoluteRect.bottom;
-// InvalidateRect((HWND)drgui_get_user_data(drgui_find_top_level_element(pElement)), &rect, FALSE);
-// }
-//
-// ...
-//
-// LRESULT CALLBACK MyWindowProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam) {
-// ...
-// drgui_element* pTopLevelElement = (drgui_element*)GetWindowLongPtr(hWnd, 0);
-// if (pTopLevelElement != NULL) {
-// switch (msg) {
-// ...
-// case WM_PAINT:
-// {
-// RECT rect;
-// if (GetUpdateRect(hWnd, &rect, FALSE)) {
-// drgui_draw(pTopLevelElement, rect.left, rect.top, rect.right - rect.left, rect.bottom - rect.top);
-// }
-//

-// QUICK NOTES
-//
-// - Text engines are used to make it easier to manage the layout of a block of text.
-// - Text engines support basic editing which requires inbound events to be posted from the higher level application.
-// - Text engines are not GUI elements. They are lower level objects that are used by higher level GUI elements.
-// - Text engines normalize line endings to \n format. Keep this in mind when retrieving the text of a layout.
-// - Text engine use the notion of a container which is used for determining which text runs are visible.

-// NOTE: This is still very much work in progress and is only being updated as I need it. You don't want to be using this library
-// in its current state.
-
-// QUICK NOTES
-// - This library does not use SSE for its basic types (vec4, etc.). Rationale: 1) It keeps things simple; 2) SSE is not always
-// faster than the FPU(s) on modern CPUs; 3) The library can always implement functions that work on __m128 variables directly
-// in the future if the need arises; 4) It doesn't work well with the pass-by-value API this library uses.
-// - Use DISABLE_SSE to disable SSE optimized functions.
-// - Angles are always specified in radians, unless otherwise noted. Rationale: Consistency with the standard library and most
-// other math libraries.
-// - Use radians() and degrees() to convert between the two.

-
-// ABOUT
-//
-// dr_mtl is a library for loading materials for use in 2D or 3D graphics. But it's a bit different to
-// what you may expect. It does not reprsent materials as a static data, but rather as a series of
-// instructions that interface with a set of inputs. Indeed, this library is more like a compiler - you
-// specify an input file (such as a Wavefront MTL file), compile it into an intermediate bytecode
-// represenation, and then run it through a code generator to generate shader code such as GLSL, HLSL,
-// Spir-V, etc.
-//
-//
-//
-// USAGE
-//
-// This is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_MTL_IMPLEMENTATION
-// #include "dr_mtl.h"
-//
-// You can then #include dr_mtl.h in other parts of the program as you would with any other header file.
-//
-//
-//
-// OPTIONS
-//
-// #define DRMTL_NO_MTL_COMPILER
-// Disables the Wavefront MTL compiler.
-//
-// #define DRMTL_NO_GLSL_CODEGEN
-// Disables the GLSL code generator.
-//
-//
-//
-// TODO
-// - Add more documentation.
-// - Add a demo to demonstrate the awesomeness of this library.
-// - Add trigonometric instructions.

-// PCX image loader. Public domain. See "unlicense" statement at the end of this file.
-// dr_pcx - v0.3.1 - 2018-09-11
-//
-// David Reid - mackron@gmail.com
-
-// USAGE
-//
-// dr_pcx is a single-file library. To use it, do something like the following in one .c file.
-// #define DR_PCX_IMPLEMENTATION
-// #include "dr_pcx.h"
-//
-// You can then #include this file in other parts of the program as you would with any other header file. Do something like
-// the following to load and decode an image:
-//
-// int width;
-// int height;
-// int components
-// drpcx_uint8* pImageData = drpcx_load_file("my_image.pcx", DRPCX_FALSE, &width, &height, &components, 0);
-// if (pImageData == NULL) {
-// // Failed to load image.
-// }
-//
-// ...
-//
-// drpcx_free(pImageData);
-//
-// The boolean parameter (second argument in the above example) is whether or not the image should be flipped upside down.
-//
-//
-//
-// OPTIONS
-// #define these options before including this file.
-//
-// #define DR_PCX_NO_STDIO
-// Disable drpcx_load_file().
-//
-//
-//
-// QUICK NOTES
-// - 2-bpp/4-plane and 4-bpp/1-plane formats have not been tested.

-Building
-========
-Move into this directory and run the build script for the relevant platform. Run from this directory.
-
- clear && ./build_opus && ./bin/dr_opus_test_0
-
-Alternatively you can compile a specific test manually:
-
- clear && gcc ./opus/dr_opus_test_0 -o ./bin/dr_opus_test_0 && ./bin/dr_opus_test_0
-
-Test vectors will be loaded from the "testvectors" folder, relative to this directory. Therefore, you need to run
-each test program from this directory:
-
- ./bin/dr_opus_test_0
-
-
-Building and Running WAV Tests
-------------------------------
-The WAV tests use libsndfile as a benchmark. The tests programs dynamically link to libsndfile at runtime which
-means you don't need to link to it at compile time. However, you will need the headers installed in a standard
-location. The batch files for the Windows build will allow you to customize the include path. On the Windows build
-you will need to drop two versions of libsndfile-1.dll into the bin directory. For the 32-bit build you need to
-name it libsndfile-1-x86.dll and for the 64-bit build you need to name it libsndfile-1-x64.dll.
-
-
-Test Vectors
-============
-In order to run certain tests you will need to download test vectors for the relevant project and place them into the
-"testvectors" folder.
-
-Opus
-----
-- Download both the original and new test vectors from https://opus-codec.org/testvectors/ and place them into
- the "testvectors/opus" folder.
-- Download the Ogg Opus test vectors from https://wiki.xiph.org/OggOpus/testvectors and place them into the
- "testvectors/opus" folder.
-- The folder structure should like like the following:
- - testvectors
- - opus
- - opus_testvectors
- - opus_newvectors
- - oggopus
- - failure_cases
- - opus_multichannel_examples
-
-FLAC
-----
-- Download the FLAC testbench from https://wiki.hydrogenaud.io/index.php?title=FLAC_decoder_testbench and place
- them into the "testvectors/flac/testbench" folder.

-:: NOTES
-::
-:: These tests use libsndfile as a benchmark. Since Windows doesn't have good standard paths for library files, this
-:: script will use "wav/include" as an additional search path for headers. You will need to place sndfile.h to the
-:: "wav/include" directory. Tests will link to libsndfile dynamically at run-time. On the Windows build you'll just
-:: need to put a copy of the 32- and 64-bit versions of libsndfile-1.dll into the "bin" directory, with the names
-:: libsndfile-1-x86.dll and libsndfile-1-x64.dll respectively. Both versions are required so that both the 32- and
-:: 64-bit builds can be tested and benchmarked.

-This is a log of my development of dr_opus - a single file public domain Opus decoder in C. The purpose of this log is
-to track the development of the project and log how I solved various problems.
-
-References:
- RFC 6716 - https://tools.ietf.org/html/rfc6716 - Definition of the Opus Audio Codec
- RFC 7845 - https://tools.ietf.org/html/rfc7845 - Ogg Encapsulation for the Opus Audio Codec
-
-
-The main reference for development is RFC 6716. An important detail with this specification is in Section 1
-
- The primary normative part of this specification is provided by the
- source code in Appendix A. Only the decoder portion of this software
- is normative, though a significant amount of code is shared by both
- the encoder and decoder. Section 6 provides a decoder conformance
- test. The decoder contains a great deal of integer and fixed-point
- arithmetic that needs to be performed exactly, including all rounding
- considerations, so any useful specification requires domain-specific
- symbolic language to adequately define these operations.
- Additionally, any conflict between the symbolic representation and
- the included reference implementation must be resolved. For the
- practical reasons of compatibility and testability, it would be
- advantageous to give the reference implementation priority in any
- disagreement. The C language is also one of the most widely
- understood, human-readable symbolic representations for machine
- behavior. For these reasons, this RFC uses the reference
- implementation as the sole symbolic representation of the codec.
-
-What this is basically saying is that the source code should be considered the main point of reference for the format of
-the Opus bit stream. We cannot, however, just willy nilly take code from the reference implementation because that would
-cause licensing problems. However, I'm going to make a prediction before I even begin: I think RFC 6716 with a bit
-intuition, problem solving and help from others it can be figured out. Indeed, I think RFC 6716 may even be enough, and
-that perhaps the authors of said specification refer to the source code as a self-defence mechanism to guard themselves
-from possible subtle errors in the specification. If I'm wrong, the log below will track it.
-
-Lets begin...

-==================
-- Inserted skeleton code with licensing information. Dual licensed as Public Domain _or_ MIT, whichever you prefer. API
- is undecided as of yet.
-- Decided on supporting C89. Not yet decided on how the standard library will be used.
-- Deciding for now to use the init() style of API from dr_wav and dr_mp3 which takes a pre-allocated decoder object. May
- need to change this to dr_flac style open() (or perhaps new()/delete()) if the size of the structure is too big.
-- dr_wav, etc. use booleans for results status so I'm copying that for consistency.
-- Added boilerplate for standard sized types (copied from mini_al).
-- Added a comment at the top of the file to show that this isn't complete (even though it's in the "wip" folder!).
-- Added boilerplate for read and seek callbacks (copied from dr_flac).
-- Added shell APIs:
- - dropus_init()
- - Not requiring onSeek for the moment because I'm hoping that we can make that optional somehow, with restriction.
- - dropus_uninit()
- - Does nothing at the moment, but in future will need to close a file when the decoder is opened against a file.
-- Added some common overrideable macros (taken from dr_flac):
- - DROPUS_ASSERT
- - DROPUS_COPY_MEMORY
- - DROPUS_ZERO_MEMORY
- - DROPUS_ZERO_OBJECT
-- Decided to use the C standard library for now. This simplifies things like memset() and assert(). Currently using the
- following headers:
- - stddef.h
- - stdint.h
- - stdlib.h
- - string.h
- - assert.h
-- Added some infrastructure for future APIs: dropus_init_file() and dropus_init_memory()
- - In dr_flac, dr_wav and dr_mp3, a mistake was made with how the internal file handle is managed by the decoder. In
- these libraries the pUserData member of the decoder structure is recycled to hold the FILE pointer. dr_opus is
- changing this to be it's own member of the main decoder structure.
- - The internal members for use with dropus_init_memory() use the same system as dr_mp3. See drmp3.memory.
-- Added dropus_init_file()
- - All init() APIs call dropus_init_internal() which is where the main initialization work is done.
- - This is using the stdio FILE API.
- - dropus_uninit() has been updated to close the file.
- - Added dropus_fopen() for compiler compatibility. Taken from dr_flac, but added the "mode" parameter for consistency
- with fopen().
- - Added dropus_fclose() for namespace consistency with dropus_fopen().
-- Added dropus_init_memory()
- - onRead and onSeek callbacks taken from dr_mp3.

-
-2018/12/01 03:58 PM
-===================
-- Decided to figure out the different encapsulations for Opus so I can figure out a design for data flow.
- - Ogg: https://tools.ietf.org/html/rfc7845
- - Matroska: https://wiki.xiph.org/MatroskaOpus
- - WebM: https://www.webmproject.org/docs/container/
- - MPEG-TS: https://wiki.xiph.org/OpusTS
- - Mysterious encapsulation used by the official test vectors. Looking at this it's hard to tell what they are using for
- this, but I'm assuming it's not documented. Will need to figure that one out for myself later.
-- Since WebM is a subset of Matroska, can we combine those together to avoid code duplication?
-- Upon reading into Ogg and MPEG-TS encapsulation (not looked into Matroska in detail yet) it looks like handling large
- channel counts is going to be a pain. It can support up to 255 channels, which are made up of multiple streams. My
- instict is telling me that we won't be able to use a fixed sized data structure and instead might require dynamic
- allocations. Darn...
-- Leaning towards a two-tier architecture - a low-level decoder for raw Opus streams, and a high-level API for encapsulated
- streams. Opus packets support only 1 or 2 channels which means the size of the structure _can_ be fixed.
- - Currently I'm thinking something like the following:
- - struct dropus_stream - low-level Opus stream decoding
- - struct dropus - high-level encapsulated Opus stream decoding
- - struct dropus_ogg (Ogg Opus)
- - struct dropus_mk (Matroska)
- - struct dropus_ts (MPEG-TS)
- - struct dropus_tv (That annoying non-standard and undocumented encapsulation used by the test vectors)
-- The maximum number of samples per frame (per-channel) is 960 because:
- - The maximum frame size for wideband (16kHz) is 60: 16*60 = 960
- - The maximum frame size for fullband (48kHz) is 20: 48*20 = 960
- - To account for stereo frames we would need to multiply 960 by 2: 960*2 = 1920
- - This is small enough that it can be stored statically inside the dropus_stream structure.
-- It looks like low level Opus streams won't be able to do efficient seeking without an encapsulation.
-- An Opus stream is made up of packets. Each packet has 1 or more frames. Each frame can be made up of 1 or 2 channels.
-- The size of the packet in bytes is unknown at the Opus stream level - it depends on the encapsulation to know the
- size of the packet. This could be a bit of a problem because we may need to know the size of a frame in order to know
- how much data we need from the client. I'm wondering if the low-level API should look something like the following:
- - dropus_result dropus_stream_decode_packet(dropus_stream* pOpusStream, const void* pCompressedData, size_t compressedDataSize);
- - This will require the caller to have information on the size of the packet.
-- Added struct dropus_stream_packet, dropus_stream_frame.
-- Each packet contains a byte that defines the structure of the packet. It's called the TOC byte
- (Section 3.1. The TOC Byte) in the RFC 6716.
-- Added skeleton implementations for dropus_stream_init() and dropus_stream_decode_packet().
-- Added helpers for decoding the different parts of TOC byte.
- - dropus_toc_config(), dropus_toc_s() and dropus_toc_c()
-- Added enum for the three different modes as outlined in Section 3.1 of RFC 6716. Also added an API to extract this
- mode from the config component of the TOC: dropus_toc_config_mode() and dropus_toc_mode().
-- Added API to extract sample rate from the TOC: dropus_toc_config_sample_rate() and dropus_toc_sample_rate()
-- Added API to extract the size of an Opus frame in PCM frames from the TOC:
- - dropus_toc_config_frame_size_in_pcm_frames() and dropus_toc_frame_size_in_pcm_frames().
-- COMMIT

-2018/12/02 09:45 AM

-- Compiling for the first time. Targetting C89 so need to get it all working property right from the start.
-- "test" folder added to my local repository. Not version controlled yet as I'm not sure I want to include all of
- the test stuff in the repository. Will definitely not be version controlling the test vectors. Perhaps use a submodule?
-- Have decided to not support the mysterious encapsulation format used by the test vectors in dr_opus itself. Instead
- I'm just doing it manually in the test program.
-- After attempting to build the C++ version, it appears Clang will attempt to #include stdint.h from Visual Studio's
- standard library which fails. May need to come up with a way to avoid the dependency on stdint.h. Same thing also
- happens with stdlib.h.
-- Have cleaned up the sized types stuff for Clang to avoid the dependency on stdint, however errors are still happening
- due to the use of stdlib.h. Leaving the Clang C++ issue for now. It's technically a Clang issue rather than dr_opus.
-- COMMIT
-- Have decided to version control test programs, but not test vectors. Instead I'm putting a note in a readme about
- where to download and place the test vectors.
-- In my experience I have found that having a testing infrastructure set up earlier saves a lot of time in the long run
- so the next thing I have decided to work on is a test program. It makes sense to test against the official test vectors,
- so the first thing is to figure out this undocumented encapsulation format...
-
-Test Vector Encapsulation Format
---------------------------------
-- All test vectors seem to start with two bytes of 0x00.
- - This does not feel like a magic number or identifier.
-- Noticed that first 4 bytes add up to a relatively small number. A counter of some kind in little endian format?
-- A pattern can be seen in testvector02.bit:
- - The bytes 00 00 00 XX can been seen repeating. This indicates some kind of blocking.
- - From the first 4 bytes you see the hex value of 0x0000001E which equals 30 in decimal
- - Counting forward 30 bytes brings us 4 bytes before the next set of 00 00 00 XX bytes. Definitely starting to feel like
- the first 4 bytes are a byte counter.
- - Skipping past those four bytes and looking at the next 00 00 00 XX bytes we get 0x0000001D which is 29 in decimal.
- - Again, counting forward by that number of bytes brings us to 4 bytes prior to the next 00 00 00 XX block. First 4
- bytes are definitely a byte counter.
-- It makes sense that each of these blocks are an Opus packet.
-- Still don't know what the second set of 4 bytes could represent... Does it matter for our purposes? All we care about
- is the raw Opus bit stream.
- - A Google search for "opus test vector format" brings up the following result (a PDF document):
- - https://www.ietf.org/proceedings/82/slides/codec-4.pdf
- - From the "Force Multipliers" page:
- - "The range coder has 32 bits of state which must match between the encoder and decoder"
- - "Provides a checksum of all encoding and decoding decisions"
- - "opus_demo bitstreams include the range value with every packet and test for mismatches"
- - Willing to bet that the extra 4 bytes are that "32 bits of state". This is actually good for dr_opus.
-- I think the format is just a list of Opus packets with 8 bytes of header data for each one:
- 4 bytes: Opus packet size in bytes
- 4 bytes: 32 bit of range coder state
- [Opus Packet]
---------------------------------
-
-- The test program can either hard code a list of vector files or we can enumerate over files in known directories. I'm
- preferring the latter to make it easier to add new vectors. It's also consistent with the way dr_flac does it which has
- been pretty good in the past.
-- Started work on a "common" lib for test programs. First thing is the new file iterator.
- - File iterator now done, but only supporting Windows currently.
-- Have implemented the logic for loading test vectors and the byte counter (and I'm assuming the range state) is actually
- in big-endian, not little-endian. I'm an idiot!
-- Copying endian management APIs from dr_flac over to dr_opus.
-- Basic infrastructure for testing against the standard test vectors is now done.
-- COMMIT

-2018/12/03 6:15 PM
-==================
-- The packet enumeration in the test program seems to work so far, but I'm still not 100% sure that my assumptions are
- correct. Adding more validation to dropus_stream_decode_packet() to increase my certainty. The next stage is to
- implement all of the main packet validation.
-- Question for later. How are "Discontinuous Transmission (DTX) or lost packet" handled? Should
- dropus_stream_decode_packet() return an error in this case?
-- Code for validating packet codes 0, 1 and 2 are now in, however untested so far. Code 3 is a bit more complicated and
- right now I need to eat dinner...
-- COMMIT
-
-2018/12/03 6:40 PM
-==================
-- Code 3 CBR is done (no VBR yet). Still untested.
-- Code 3 VBR is done. Still untested.
-- Testing and debugging against the standard test vectors coming next.
-- Fixed a few compiler warnings.
-- COMMIT
-
-2019/03/08 6:28 PM
-==================
-- Starting on range decoding. From figure 4 in RFC 6716 the diagram shows that both the SILK and CELT decoders draw
- their data from the Range Decoder. Therefore the Range Decoder needs to be figured out before SILK and CELT decoding.
- I have no prior knowledge on range coding, so hopefully RFC 6716 has enough information for a complete enough
- implementation for purpose of Opus decoding.
-- Section 4.1.1 of RGC 6716 is how to initialize the decoder. It references a variable called "rng", but doesn't
- specificy it's possible ranges. Setting to a 32-bit unsigned integer for now.
- - In this section, it says "or containing zero if there are no bytes in this Opus frame". I'm assuming we do this
- by looping over each frame in order...
- - Just noticed that the end of section 4.1.1 says "rng > 2**23". So "rng" needs to be 32-bits.
-- And now I've just noticed that section 4.1 explicitly says the following: "Both val and rng are 32-bit unsigned integer
- values." Problem solved.
-- Having read over the range coding stuff in RFC 6716 I had some difficulty figuring out where symbols frequencies are
- being stored. They're not stored, but rather specified in the specification in a per-context basis. In the spec there
- are references to "PDFs" which is like this "{f[0], f[1]}/ft". Example: "{1, 1}/2". Simple, now that I've finally
- figured it out...
-- I can therefore not do the range decoder independant of some higher level context. I will start with the SILK decoder
- since that's the next section...
-
-2019/03/09 6:52 AM
-==================
-- I think I'm getting a feel for the requirements for the range decoding API. I've decided for now to use a structure
- for this called dropus_range_decoder.
-- dropus_range_decoder_init() implemented based on section 4.1.1.
-- Added stub for dropus_stream_decode_frame(). I think the idea is that we iterate over each frame in the packet and
- decode them in order? Not fully sure yet how frame transitions will work, so may need to rethink this.
-- I'm still not sure if the range decoder is supposed to be initialized once per frame or once per packet...
-- After more testing it turns out my test program wasn't reporting errors properly. *Sigh*. These bugs were originating
- from the packet decoding section.
-- COMMIT
-- Section 4.1.2 mentions that there's two steps to decoding a symbol. The first step seems easy enough. Implemented in
- dropus_range_decoder_fs().
-- The second step requires updating "val" and "rng" of the range decoder based on (fl[k], fh[k] and ft). Implemented in
- dropus_range_decoder_update(pRangeDecoder, fl, fh, ft).
-- Normalization of the range decoder is easy (RFC 6716 - 4.1.2.1). Implemented in dropus_range_decoder_normalize().
-- I think at this point we have the foundations done for the range decoder. Still more to do for CELT, but I think I
- now have enough to hack away a bit more at the SILK-specific data.
-- COMMIT
-- I'm still not 100% sure how range decoding works - I know it depends on the context of the specific thing being
- decoded, but not sure how the index "k" is handled. The first part of the SILK frame is the VAD flags PDF={1,1}/2.
- Do I use the value of k (which I think is 0 or 1) to know whether or not the bit is set? I am going to assume this
- for now.
-
-2019/03/10 7:40 AM
-==================
-- At the moment I am using what feels like a very cumbersome way of decoding "k" from the range decoder. I'm calling
- dropus_range_decoder_fs(), followed by a function called dropus_range_decoder_k() to retrieve "k", and then
- dropus_range_decoder_update() at the end of it. I can simplify this into a single function, I think, which I'm
- calling dropus_range_decode() which will perform the "fs" decode, perform the update, then return "k".
-- As I'm writing dropus_range_decoder_decode() I've realized that I can simplify my dropus_range_decoder_update()
- function to do both the "k" lookup and the the update from section 4.1.2. It just needs to be changed to take
- the "context" probabilities and "fs" and to return "k".
-- This _seems_ to work. Or at least, the results are consistent with my first attempt. Committing.
-- Added dropus_Q13() for doing the stereo weight lookup (RFC 7616 - Table 7).
-- Section 4.2.7.1 mentions that the weights are linearly interpolated with the weights from the previous frame. What
- factor do I use for the interpolation?
-- Finished initial work on RFC 7616 - Section 4.2.7.1. Still don't know how the interpolation part works. I'm hoping
- this is explained later in the spec.
-- COMMIT
-- Completed initial implementation of RFC 7616 - Section 4.2.7.2.

-2020/03/29 6:33 AM
-==================
-- After a whole year, time to take another look at this. Only problem is, I've forgotten everything! Let's do a
- quick pass on the high level stuff to get it consistent with dr_flac. Two mistakes I made with dr_flac: Not having
- a low-level API that works on the FLAC frame level; and returning booleans instead of result codes. The first one
- is already being handled, but lets update the high level APIs to use result codes.
-- High level APIs now updated to return result codes.
-- People are going to want to log errors: added dropus_result_description() to retrieve a human readable description
- of a result code for logging and error reporting purposes.
-- I've had reports of people having compilation errors with inlining before. Need to bring over the INLINE macro from
- dr_flac to ensure we don't get more reports about that.
-- I've had people request the ability to customize whether or not public APIs are marked as static or extern in other
- libraries, so adding the DROPUS_API decoration. It's better to do this sooner than later, because this happened with
- miniaudio recently which was a ~40K line library at the time, and it was nightmare to update!
-- There will be a requirement to allocate memory for high level APIs. Support for allocation macros and allocation
- callbacks need to be added now so we can avoid breaking APIs later.
-- There have been requests in the past to support loading files from a wchar_t encoded path. Adding support by pulling
- in custom fopen() and wfopen() implementations from dr_flac.
-- Have not yet compiled on VC6 so lets do a pass on that to make it easier for us later.
-- VC6 is now compiling clean. Time to check GCC and Clang in strict C89 mode.
-- Getting compiler errors about some Linux specific code for handling byte swaps. Removed and replaced with a cross-
- platform solution.
-- From what I can see it looks like our boilerplate is now up to date with dr_flac, dr_wav and dr_mp3. Time to get onto
- some actual Opus decoding.
-- Looks like a typo in dropus_range_decoder_update() for handling the `fl[k] > 0` case. Changed this, but now getting
- a division by zero. Debugging...
- - And fixed. The last paragraph in RFC 6716 - Section 4.1.2 is the part I was missing:
- After the updates, implemented by ec_dec_update() (entdec.c), the
- decoder normalizes the range using the procedure in the next section,
- and returns the index k.
-- Reading through dropus_stream_decode_packet() to refresh my memory and some stuff needs cleaning up. Important from
- now on to distinguish between PCM frames and Opus frames. All variables referring to one of the other needs to be
- prefixed with "pcm" or "opus", depending on it's use. Example: opusFrameCount / pcmFrameCount.
-- Added infrastructure for handling CELT and Hybrid frames when the time comes. For now still focused on getting SILK
- frames working.
-- Reviewing SILK decoding logic to refresh my memory and looks like I've misinterpreted the encoding for per-frame
- LBRR flags. When there's more than one SILK frame, the first LBRR flag is just used to determine whether or not
- the per-frame LBRR flags is present. I was _always_ reading the LBRR flags regardless of the value of the primary
- LBRR flag.
-
-2020/03/30 7:30 AM
-==================
-- The decoding of SILK frames needs to be put in their own function in order to handle LBRR and regular SILK frames.
- Looking at the spec, there's some complicated branching logic for determine what needs to be decoded. I've put in
- a rough draft as a start, but needs some work. Will continue on this later.

-## Language Binding Generation Scripts
-
-> REMINDER: we can pass `-fparse-all-comments` to the clang ast-dump command line which adds the following node types to the ast-dump.json: FullComment, ParagraphComment, TextComment. This might allow us to preserve comments in the language bindings (might be useful as part of a bigger change to make sokol header comments autodoc and Intellisense-friendly)
-
-### Zig
-
-First make sure that clang and python3 are in the path:
-
-```
-> clang --version
-> python3 --version
-```
-
-...on Windows I simply install those with scoop:
-
-```
-> scoop install llvm
-> scoop install python
-```
-
-To update the Zig bindings:
-
-```
-> cd sokol/bindgen
-> git clone https://github.com/floooh/sokol-zig
-> git clone https://github.com/floooh/sokol-nim
-> git clone https://github.com/floooh/sokol-odin
-> git clone https://github.com/floooh/sokol-rust
-> python3 gen_all.py
-```
-
-Test and run samples:
-
-```
-> cd sokol/bindgen/sokol-zig
-> zig build run-clear
-> zig build run-triangle
-> zig build run-cube
-...
-```

-/// ## About
-/// This is a minimal state immediate mode graphical user interface toolkit
-/// written in ANSI C and licensed under public domain. It was designed as a simple
-/// embeddable user interface for application and does not have any dependencies,
-/// a default renderbackend or OS window and input handling but instead provides a very modular
-/// library approach by using simple input state for input and draw
-/// commands describing primitive shapes as output. So instead of providing a
-/// layered library that tries to abstract over a number of platform and
-/// render backends it only focuses on the actual UI.
-///
-/// ## Highlights
-/// - Graphical user interface toolkit
-/// - Single header library
-/// - Written in C89 (a.k.a. ANSI C or ISO C90)
-/// - Small codebase (~18kLOC)
-/// - Focus on portability, efficiency and simplicity
-/// - No dependencies (not even the standard library if not wanted)
-/// - Fully skinnable and customizable
-/// - Low memory footprint with total memory control if needed or wanted
-/// - UTF-8 support
-/// - No global or hidden state
-/// - Customizable library modules (you can compile and use only what you need)
-/// - Optional font baker and vertex buffer output
-///
-/// ## Features
-/// - Absolutely no platform dependent code
-/// - Memory management control ranging from/to
-/// - Ease of use by allocating everything from standard library
-/// - Control every byte of memory inside the library
-/// - Font handling control ranging from/to
-/// - Use your own font implementation for everything
-/// - Use this libraries internal font baking and handling API
-/// - Drawing output control ranging from/to
-/// - Simple shapes for more high level APIs which already have drawing capabilities
-/// - Hardware accessible anti-aliased vertex buffer output
-/// - Customizable colors and properties ranging from/to
-/// - Simple changes to color by filling a simple color table
-/// - Complete control with ability to use skinning to decorate widgets
-/// - Bendable UI library with widget ranging from/to
-/// - Basic widgets like buttons, checkboxes, slider, ...
-/// - Advanced widget like abstract comboboxes, contextual menus,...
-/// - Compile time configuration to only compile what you need
-/// - Subset which can be used if you do not want to link or use the standard library
-/// - Can be easily modified to only update on user input instead of frame updates
-///
-/// ## Usage
-/// This library is self contained in one single header file and can be used either
-/// in header only mode or in implementation mode. The header only mode is used
-/// by default when included and allows including this header in other headers
-/// and does not contain the actual implementation.
-///
-/// The implementation mode requires to define the preprocessor macro
-/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C
-/// #define NK_IMPLEMENTATION
-/// #include "nuklear.h"
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
-/// below in header and implementation mode if you want to use additional functionality
-/// or need more control over the library.
-///
-/// !!! WARNING
-/// Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions.
-///
-/// ### Flags
-/// Flag | Description
-/// --------------------------------|------------------------------------------
-/// NK_PRIVATE | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation
-/// NK_INCLUDE_FIXED_TYPES | If defined it will include header `` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself.
-/// NK_INCLUDE_DEFAULT_ALLOCATOR | If defined it will include header `` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management.
-/// NK_INCLUDE_STANDARD_IO | If defined it will include header `` and provide additional functions depending on file loading.
-/// NK_INCLUDE_STANDARD_VARARGS | If defined it will include header and provide additional functions depending on file loading.
-/// NK_INCLUDE_STANDARD_BOOL | If defined it will include header `` for nk_bool otherwise nuklear defines nk_bool as int.
-/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,...
-/// NK_INCLUDE_FONT_BAKING | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it.
-/// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
-/// NK_INCLUDE_COMMAND_USERDATA | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures.
-/// NK_BUTTON_TRIGGER_ON_RELEASE | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released.
-/// NK_ZERO_COMMAND_MEMORY | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame.
-/// NK_UINT_DRAW_INDEX | Defining this will set the size of vertex index elements when using NK_VERTEX_BUFFER_OUTPUT to 32bit instead of the default of 16bit
-/// NK_KEYSTATE_BASED_INPUT | Define this if your backend uses key state for each frame rather than key press/release events
-///
-/// !!! WARNING
-/// The following flags will pull in the standard C library:
-/// - NK_INCLUDE_DEFAULT_ALLOCATOR
-/// - NK_INCLUDE_STANDARD_IO
-/// - NK_INCLUDE_STANDARD_VARARGS
-///
-/// !!! WARNING
-/// The following flags if defined need to be defined for both header and implementation:
-/// - NK_INCLUDE_FIXED_TYPES
-/// - NK_INCLUDE_DEFAULT_ALLOCATOR
-/// - NK_INCLUDE_STANDARD_VARARGS
-/// - NK_INCLUDE_STANDARD_BOOL
-/// - NK_INCLUDE_VERTEX_BUFFER_OUTPUT
-/// - NK_INCLUDE_FONT_BAKING
-/// - NK_INCLUDE_DEFAULT_FONT
-/// - NK_INCLUDE_STANDARD_VARARGS
-/// - NK_INCLUDE_COMMAND_USERDATA
-/// - NK_UINT_DRAW_INDEX
-///
-/// ### Constants
-/// Define | Description
-/// --------------------------------|---------------------------------------
-/// NK_BUFFER_DEFAULT_INITIAL_SIZE | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it.
-/// NK_MAX_NUMBER_BUFFER | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient.
-/// NK_INPUT_MAX | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient.
-///
-/// !!! WARNING
-/// The following constants if defined need to be defined for both header and implementation:
-/// - NK_MAX_NUMBER_BUFFER
-/// - NK_BUFFER_DEFAULT_INITIAL_SIZE
-/// - NK_INPUT_MAX
-///
-/// ### Dependencies
-/// Function | Description
-/// ------------|---------------------------------------------------------------
-/// NK_ASSERT | If you don't define this, nuklear will use with assert().
-/// NK_MEMSET | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version.
-/// NK_MEMCPY | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version.
-/// NK_SQRT | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version.
-/// NK_SIN | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation.
-/// NK_COS | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation.
-/// NK_STRTOD | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
-/// NK_DTOA | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
-/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe.
-///
-/// !!! WARNING
-/// The following dependencies will pull in the standard C library if not redefined:
-/// - NK_ASSERT
-///
-/// !!! WARNING
-/// The following dependencies if defined need to be defined for both header and implementation:
-/// - NK_ASSERT
-///
-/// !!! WARNING
-/// The following dependencies if defined need to be defined only for the implementation part:
-/// - NK_MEMSET
-/// - NK_MEMCPY
-/// - NK_SQRT
-/// - NK_SIN
-/// - NK_COS
-/// - NK_STRTOD
-/// - NK_DTOA
-/// - NK_VSNPRINTF
-///
-/// ## Example
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// // init gui state
-/// enum {EASY, HARD};
-/// static int op = EASY;
-/// static float value = 0.6f;
-/// static int i = 20;
-/// struct nk_context ctx;
-///
-/// nk_init_fixed(&ctx, calloc(1, MAX_MEMORY), MAX_MEMORY, &font);
-/// if (nk_begin(&ctx, "Show", nk_rect(50, 50, 220, 220),
-/// NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_CLOSABLE)) {
-/// // fixed widget pixel width
-/// nk_layout_row_static(&ctx, 30, 80, 1);
-/// if (nk_button_label(&ctx, "button")) {
-/// // event handling
-/// }
-///
-/// // fixed widget window ratio width
-/// nk_layout_row_dynamic(&ctx, 30, 2);
-/// if (nk_option_label(&ctx, "easy", op == EASY)) op = EASY;
-/// if (nk_option_label(&ctx, "hard", op == HARD)) op = HARD;
-///
-/// // custom widget pixel width
-/// nk_layout_row_begin(&ctx, NK_STATIC, 30, 2);
-/// {
-/// nk_layout_row_push(&ctx, 50);
-/// nk_label(&ctx, "Volume:", NK_TEXT_LEFT);
-/// nk_layout_row_push(&ctx, 110);
-/// nk_slider_float(&ctx, 0, &value, 1.0f, 0.1f);
-/// }
-/// nk_layout_row_end(&ctx);
-/// }
-/// nk_end(&ctx);

-/*/// ### Context
-/// Contexts are the main entry point and the majestro of nuklear and contain all required state.
-/// They are used for window, memory, input, style, stack, commands and time management and need
-/// to be passed into all nuklear GUI specific functions.
-///
-/// #### Usage
-/// To use a context it first has to be initialized which can be achieved by calling
-/// one of either `nk_init_default`, `nk_init_fixed`, `nk_init`, `nk_init_custom`.
-/// Each takes in a font handle and a specific way of handling memory. Memory control
-/// hereby ranges from standard library to just specifying a fixed sized block of memory
-/// which nuklear has to manage itself from.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// struct nk_context ctx;
-/// nk_init_xxx(&ctx, ...);
-/// while (1) {
-/// // [...]
-/// nk_clear(&ctx);
-/// }
-/// nk_free(&ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// #### Reference
-/// Function | Description
-/// --------------------|-------------------------------------------------------
-/// __nk_init_default__ | Initializes context with standard library memory allocation (malloc,free)
-/// __nk_init_fixed__ | Initializes context from single fixed size memory block
-/// __nk_init__ | Initializes context with memory allocator callbacks for alloc and free
-/// __nk_init_custom__ | Initializes context from two buffers. One for draw commands the other for window/panel/table allocations
-/// __nk_clear__ | Called at the end of the frame to reset and prepare the context for the next frame
-/// __nk_free__ | Shutdown and free all memory allocated inside the context
-/// __nk_set_user_data__| Utility function to pass user data to draw command

-/*/// ### Input
-/// The input API is responsible for holding the current input state composed of
-/// mouse, key and text input states.
-/// It is worth noting that no direct OS or window handling is done in nuklear.
-/// Instead all input state has to be provided by platform specific code. This on one hand
-/// expects more work from the user and complicates usage but on the other hand
-/// provides simple abstraction over a big number of platforms, libraries and other
-/// already provided functionality.

-/// else if (evt.type == [...]) {
-/// // [...]
-/// }
-/// } nk_input_end(&ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// #### Usage
-/// Input state needs to be provided to nuklear by first calling `nk_input_begin`
-/// which resets internal state like delta mouse position and button transistions.
-/// After `nk_input_begin` all current input state needs to be provided. This includes
-/// mouse motion, button and key pressed and released, text input and scrolling.
-/// Both event- or state-based input handling are supported by this API
-/// and should work without problems. Finally after all input state has been
-/// mirrored `nk_input_end` needs to be called to finish input process.

- * DRAWING
- *
- * =============================================================================*/
-/*/// ### Drawing
-/// This library was designed to be render backend agnostic so it does
-/// not draw anything to screen directly. Instead all drawn shapes, widgets
-/// are made of, are buffered into memory and make up a command queue.
-/// Each frame therefore fills the command buffer with draw commands
-/// that then need to be executed by the user and his own render backend.
-/// After that the command buffer needs to be cleared and a new frame can be
-/// started. It is probably important to note that the command buffer is the main
-/// drawing API and the optional vertex buffer API only takes this format and
-/// converts it into a hardware accessible format.
-///
-/// #### Usage
-/// To draw all draw commands accumulated over a frame you need your own render
-/// backend able to draw a number of 2D primitives. This includes at least
-/// filled and stroked rectangles, circles, text, lines, triangles and scissors.
-/// As soon as this criterion is met you can iterate over each draw command
-/// and execute each draw command in a interpreter like fashion:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// switch (cmd->type) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case //...:
-/// //[...]
-/// }
-/// }
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// In program flow context draw commands need to be executed after input has been
-/// gathered and the complete UI with windows and their contained widgets have
-/// been executed and before calling `nk_clear` which frees all previously
-/// allocated draw commands.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// struct nk_context ctx;
-/// nk_init_xxx(&ctx, ...);
-/// while (1) {
-/// Event evt;
-/// nk_input_begin(&ctx);
-/// while (GetEvent(&evt)) {
-/// if (evt.type == MOUSE_MOVE)
-/// nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
-/// else if (evt.type == [...]) {
-/// [...]
-/// }
-/// }
-/// nk_input_end(&ctx);
-/// //
-/// // [...]
-/// //
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// switch (cmd->type) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case ...:
-/// // [...]
-/// }
-/// nk_clear(&ctx);
-/// }
-/// nk_free(&ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// You probably noticed that you have to draw all of the UI each frame which is
-/// quite wasteful. While the actual UI updating loop is quite fast rendering
-/// without actually needing it is not. So there are multiple things you could do.
-///
-/// First is only update on input. This of course is only an option if your
-/// application only depends on the UI and does not require any outside calculations.
-/// If you actually only update on input make sure to update the UI two times each
-/// frame and call `nk_clear` directly after the first pass and only draw in
-/// the second pass. In addition it is recommended to also add additional timers
-/// to make sure the UI is not drawn more than a fixed number of frames per second.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// struct nk_context ctx;
-/// nk_init_xxx(&ctx, ...);
-/// while (1) {
-/// // [...wait for input ]
-/// // [...do two UI passes ...]
-/// do_ui(...)
-/// nk_clear(&ctx);
-/// do_ui(...)
-/// //
-/// // draw
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// switch (cmd->type) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case ...:
-/// //[...]
-/// }
-/// nk_clear(&ctx);
-/// }
-/// nk_free(&ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// The second probably more applicable trick is to only draw if anything changed.
-/// It is not really useful for applications with continuous draw loop but
-/// quite useful for desktop applications. To actually get nuklear to only
-/// draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and
-/// allocate a memory buffer that will store each unique drawing output.
-/// After each frame you compare the draw command memory inside the library
-/// with your allocated buffer by memcmp. If memcmp detects differences
-/// you have to copy the command buffer into the allocated buffer
-/// and then draw like usual (this example uses fixed memory but you could
-/// use dynamically allocated memory).
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// //[... other defines ...]
-/// #define NK_ZERO_COMMAND_MEMORY
-/// #include "nuklear.h"
-/// //
-/// // setup context
-/// struct nk_context ctx;
-/// void *last = calloc(1,64*1024);
-/// void *buf = calloc(1,64*1024);
-/// nk_init_fixed(&ctx, buf, 64*1024);
-/// //
-/// // loop
-/// while (1) {
-/// // [...input...]
-/// // [...ui...]
-/// void *cmds = nk_buffer_memory(&ctx.memory);
-/// if (memcmp(cmds, last, ctx.memory.allocated)) {
-/// memcpy(last,cmds,ctx.memory.allocated);
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// switch (cmd->type) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case ...:
-/// // [...]
-/// }
-/// }
-/// }
-/// nk_clear(&ctx);
-/// }
-/// nk_free(&ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// Finally while using draw commands makes sense for higher abstracted platforms like
-/// X11 and Win32 or drawing libraries it is often desirable to use graphics
-/// hardware directly. Therefore it is possible to just define
-/// `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output.
-/// To access the vertex output you first have to convert all draw commands into
-/// vertexes by calling `nk_convert` which takes in your preferred vertex format.
-/// After successfully converting all draw commands just iterate over and execute all
-/// vertex draw commands:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// // fill configuration
-/// struct your_vertex
-/// {
-/// float pos[2]; // important to keep it to 2 floats
-/// float uv[2];
-/// unsigned char col[4];

-/// {NK_VERTEX_COLOR, NK_FORMAT_R8G8B8A8, NK_OFFSETOF(struct your_vertex, col)},
-/// {NK_VERTEX_LAYOUT_END}
-/// };
-/// cfg.shape_AA = NK_ANTI_ALIASING_ON;
-/// cfg.line_AA = NK_ANTI_ALIASING_ON;
-/// cfg.vertex_layout = vertex_layout;
-/// cfg.vertex_size = sizeof(struct your_vertex);
-/// cfg.vertex_alignment = NK_ALIGNOF(struct your_vertex);
-/// cfg.circle_segment_count = 22;
-/// cfg.curve_segment_count = 22;
-/// cfg.arc_segment_count = 22;
-/// cfg.global_alpha = 1.0f;
-/// cfg.null = dev->null;
-/// //
-/// // setup buffers and convert

- * WINDOW
- *
- * =============================================================================
-/// ### Window
-/// Windows are the main persistent state used inside nuklear and are life time
-/// controlled by simply "retouching" (i.e. calling) each window each frame.
-/// All widgets inside nuklear can only be added inside the function pair `nk_begin_xxx`
-/// and `nk_end`. Calling any widgets outside these two functions will result in an
-/// assert in debug or no state change in release mode.
-///
-/// Each window holds frame persistent state like position, size, flags, state tables,
-/// and some garbage collected internal persistent widget state. Each window
-/// is linked into a window stack list which determines the drawing and overlapping
-/// order. The topmost window thereby is the currently active window.
-///
-/// To change window position inside the stack occurs either automatically by
-/// user input by being clicked on or programmatically by calling `nk_window_focus`.
-/// Windows by default are visible unless explicitly being defined with flag
-/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag
-/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling
-/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.
-///
-/// #### Usage
-/// To create and keep a window you have to call one of the two `nk_begin_xxx`
-/// functions to start window declarations and `nk_end` at the end. Furthermore it
-/// is recommended to check the return value of `nk_begin_xxx` and only process
-/// widgets inside the window if the value is not 0. Either way you have to call
-/// `nk_end` at the end of window declarations. Furthermore, do not attempt to
-/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not
-/// in a segmentation fault.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // [... widgets ...]
-/// }
-/// nk_end(ctx);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// In the grand concept window and widget declarations need to occur after input
-/// handling and before drawing to screen. Not doing so can result in higher
-/// latency or at worst invalid behavior. Furthermore make sure that `nk_clear`
-/// is called at the end of the frame. While nuklear's default platform backends
-/// already call `nk_clear` for you if you write your own backend not calling
-/// `nk_clear` can cause asserts or even worse undefined behavior.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// struct nk_context ctx;
-/// nk_init_xxx(&ctx, ...);
-/// while (1) {
-/// Event evt;
-/// nk_input_begin(&ctx);
-/// while (GetEvent(&evt)) {
-/// if (evt.type == MOUSE_MOVE)
-/// nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
-/// else if (evt.type == [...]) {
-/// nk_input_xxx(...);
-/// }
-/// }
-/// nk_input_end(&ctx);
-///
-/// if (nk_begin_xxx(...) {
-/// //[...]
-/// }
-/// nk_end(ctx);
-///
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case //...:

- * LAYOUT
- *
- * =============================================================================
-/// ### Layouting
-/// Layouting in general describes placing widget inside a window with position and size.
-/// While in this particular implementation there are five different APIs for layouting
-/// each with different trade offs between control and ease of use.
-///
-/// All layouting methods in this library are based around the concept of a row.
-/// A row has a height the window content grows by and a number of columns and each
-/// layouting method specifies how each widget is placed inside the row.
-/// After a row has been allocated by calling a layouting functions and then
-/// filled with widgets will advance an internal pointer over the allocated row.
-///
-/// To actually define a layout you just call the appropriate layouting function
-/// and each subsequent widget call will place the widget as specified. Important
-/// here is that if you define more widgets then columns defined inside the layout
-/// functions it will allocate the next row without you having to make another layouting
-/// call.
-///
-/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API
-/// is that you have to define the row height for each. However the row height
-/// often depends on the height of the font.
-///
-/// To fix that internally nuklear uses a minimum row height that is set to the
-/// height plus padding of currently active font and overwrites the row height
-/// value if zero.
-///
-/// If you manually want to change the minimum row height then
-/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to
-/// reset it back to be derived from font height.
-///
-/// Also if you change the font in nuklear it will automatically change the minimum
-/// row height for you and. This means if you change the font but still want
-/// a minimum row height smaller than the font you have to repush your value.
-///
-/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx`
-/// layouting method in combination with a cassowary constraint solver (there are
-/// some versions on github with permissive license model) to take over all control over widget
-/// layouting yourself. However for quick and dirty layouting using all the other layouting
-/// functions should be fine.
-///
-/// #### Usage
-/// 1. __nk_layout_row_dynamic__
-/// The easiest layouting function is `nk_layout_row_dynamic`. It provides each
-/// widgets with same horizontal space inside the row and dynamically grows
-/// if the owning window grows in width. So the number of columns dictates
-/// the size of each widget dynamically by formula:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// widget_width = (window_width - padding - spacing) * (1/colum_count)
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// Just like all other layouting APIs if you define more widget than columns this
-/// library will allocate a new row and keep all layouting parameters previously
-/// defined.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // first row with height: 30 composed of two widgets
-/// nk_layout_row_dynamic(&ctx, 30, 2);
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // second row with same parameter as defined above
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // third row uses 0 for height which will use auto layouting
-/// nk_layout_row_dynamic(&ctx, 0, 2);
-/// nk_widget(...);
-/// nk_widget(...);
-/// }
-/// nk_end(...);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// 2. __nk_layout_row_static__
-/// Another easy layouting function is `nk_layout_row_static`. It provides each
-/// widget with same horizontal pixel width inside the row and does not grow
-/// if the owning window scales smaller or bigger.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // first row with height: 30 composed of two widgets with width: 80
-/// nk_layout_row_static(&ctx, 30, 80, 2);
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // second row with same parameter as defined above
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // third row uses 0 for height which will use auto layouting
-/// nk_layout_row_static(&ctx, 0, 80, 2);
-/// nk_widget(...);
-/// nk_widget(...);
-/// }
-/// nk_end(...);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// 3. __nk_layout_row_xxx__
-/// A little bit more advanced layouting API are functions `nk_layout_row_begin`,
-/// `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly
-/// specify each column pixel or window ratio in a row. It supports either
-/// directly setting per column pixel width or widget window ratio but not
-/// both. Furthermore it is a immediate mode API so each value is directly
-/// pushed before calling a widget. Therefore the layout is not automatically
-/// repeating like the last two layouting functions.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // first row with height: 25 composed of two widgets with width 60 and 40
-/// nk_layout_row_begin(ctx, NK_STATIC, 25, 2);
-/// nk_layout_row_push(ctx, 60);
-/// nk_widget(...);
-/// nk_layout_row_push(ctx, 40);
-/// nk_widget(...);
-/// nk_layout_row_end(ctx);
-/// //
-/// // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75
-/// nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2);
-/// nk_layout_row_push(ctx, 0.25f);
-/// nk_widget(...);
-/// nk_layout_row_push(ctx, 0.75f);
-/// nk_widget(...);
-/// nk_layout_row_end(ctx);
-/// //
-/// // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75
-/// nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2);
-/// nk_layout_row_push(ctx, 0.25f);
-/// nk_widget(...);
-/// nk_layout_row_push(ctx, 0.75f);
-/// nk_widget(...);
-/// nk_layout_row_end(ctx);
-/// }
-/// nk_end(...);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// 4. __nk_layout_row__
-/// The array counterpart to API nk_layout_row_xxx is the single nk_layout_row
-/// functions. Instead of pushing either pixel or window ratio for every widget
-/// it allows to define it by array. The trade of for less control is that
-/// `nk_layout_row` is automatically repeating. Otherwise the behavior is the
-/// same.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // two rows with height: 30 composed of two widgets with width 60 and 40
-/// const float size[] = {60,40};
-/// nk_layout_row(ctx, NK_STATIC, 30, 2, ratio);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75
-/// const float ratio[] = {0.25, 0.75};
-/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// //
-/// // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75
-/// const float ratio[] = {0.25, 0.75};
-/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// }
-/// nk_end(...);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// 5. __nk_layout_row_template_xxx__
-/// The most complex and second most flexible API is a simplified flexbox version without
-/// line wrapping and weights for dynamic widgets. It is an immediate mode API but
-/// unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called
-/// before calling the templated widgets.
-/// The row template layout has three different per widget size specifier. The first
-/// one is the `nk_layout_row_template_push_static` with fixed widget pixel width.
-/// They do not grow if the row grows and will always stay the same.
-/// The second size specifier is `nk_layout_row_template_push_variable`
-/// which defines a minimum widget size but it also can grow if more space is available
-/// not taken by other widgets.
-/// Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic`
-/// which are completely flexible and unlike variable widgets can even shrink
-/// to zero if not enough space is provided.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // two rows with height: 30 composed of three widgets
-/// nk_layout_row_template_begin(ctx, 30);
-/// nk_layout_row_template_push_dynamic(ctx);
-/// nk_layout_row_template_push_variable(ctx, 80);
-/// nk_layout_row_template_push_static(ctx, 80);
-/// nk_layout_row_template_end(ctx);
-/// //
-/// // first row
-/// nk_widget(...); // dynamic widget can go to zero if not enough space
-/// nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space
-/// nk_widget(...); // static widget with fixed 80 pixel width
-/// //
-/// // second row same layout
-/// nk_widget(...);
-/// nk_widget(...);
-/// nk_widget(...);
-/// }
-/// nk_end(...);
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// 6. __nk_layout_space_xxx__
-/// Finally the most flexible API directly allows you to place widgets inside the
-/// window. The space layout API is an immediate mode API which does not support
-/// row auto repeat and directly sets position and size of a widget. Position
-/// and size hereby can be either specified as ratio of allocated space or
-/// allocated space local position and pixel size. Since this API is quite
-/// powerful there are a number of utility functions to get the available space
-/// and convert between local allocated space and screen space.
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_begin_xxx(...) {
-/// // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
-/// nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX);
-/// nk_layout_space_push(ctx, nk_rect(0,0,150,200));
-/// nk_widget(...);
-/// nk_layout_space_push(ctx, nk_rect(200,200,100,200));
-/// nk_widget(...);
-/// nk_layout_space_end(ctx);
-/// //
-/// // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
-/// nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX);
-/// nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1));
-/// nk_widget(...);
-/// nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1));
-/// nk_widget(...);
-/// }
-/// nk_end(...);

- * GROUP
- *
- * =============================================================================
-/// ### Groups
-/// Groups are basically windows inside windows. They allow to subdivide space
-/// in a window to layout widgets as a group. Almost all more complex widget
-/// layouting requirements can be solved using groups and basic layouting
-/// fuctionality. Groups just like windows are identified by an unique name and
-/// internally keep track of scrollbar offsets by default. However additional
-/// versions are provided to directly manage the scrollbar.
-///
-/// #### Usage
-/// To create a group you have to call one of the three `nk_group_begin_xxx`
-/// functions to start group declarations and `nk_group_end` at the end. Furthermore it
-/// is required to check the return value of `nk_group_begin_xxx` and only process
-/// widgets inside the window if the value is not 0.
-/// Nesting groups is possible and even encouraged since many layouting schemes
-/// can only be achieved by nesting. Groups, unlike windows, need `nk_group_end`
-/// to be only called if the corosponding `nk_group_begin_xxx` call does not return 0:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// if (nk_group_begin_xxx(ctx, ...) {
-/// // [... widgets ...]
-/// nk_group_end(ctx);
-/// }
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-///
-/// In the grand concept groups can be called after starting a window
-/// with `nk_begin_xxx` and before calling `nk_end`:
-///
-/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
-/// struct nk_context ctx;
-/// nk_init_xxx(&ctx, ...);
-/// while (1) {
-/// // Input
-/// Event evt;
-/// nk_input_begin(&ctx);
-/// while (GetEvent(&evt)) {
-/// if (evt.type == MOUSE_MOVE)
-/// nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
-/// else if (evt.type == [...]) {
-/// nk_input_xxx(...);
-/// }
-/// }
-/// nk_input_end(&ctx);
-/// //
-/// // Window
-/// if (nk_begin_xxx(...) {
-/// // [...widgets...]
-/// nk_layout_row_dynamic(...);
-/// if (nk_group_begin_xxx(ctx, ...) {
-/// //[... widgets ...]
-/// nk_group_end(ctx);
-/// }
-/// }
-/// nk_end(ctx);
-/// //
-/// // Draw
-/// const struct nk_command *cmd = 0;
-/// nk_foreach(cmd, &ctx) {
-/// switch (cmd->type) {
-/// case NK_COMMAND_LINE:
-/// your_draw_line_function(...)
-/// break;
-/// case NK_COMMAND_RECT
-/// your_draw_rect_function(...)
-/// break;
-/// case ...:
-/// // [...]
-/// }

-/// }

- * TREE
- *
- * =============================================================================
-/// ### Tree
-/// Trees represent two different concept. First the concept of a collapsable
-/// UI section that can be either in a hidden or visibile state. They allow the UI
-/// user to selectively minimize the current set of visible UI to comprehend.
-/// The second concept are tree widgets for visual UI representation of trees.
-///
-/// Trees thereby can be nested for tree representations and multiple nested
-/// collapsable UI sections. All trees are started by calling of the
-/// `nk_tree_xxx_push_tree` functions and ended by calling one of the
-/// `nk_tree_xxx_pop_xxx()` functions. Each starting functions takes a title label
-/// and optionally an image to be displayed and the initial collapse state from
-/// the nk_collapse_states section.
-///
-/// The runtime state of the tree is either stored outside the library by the caller
-/// or inside which requires a unique ID. The unique ID can either be generated
-/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`,
-/// by `__FILE__` and a user provided ID generated for example by loop index with
-/// function `nk_tree_push_id` or completely provided from outside by user with
-/// function `nk_tree_push_hashed`.
-///
-/// #### Usage
-/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx`
-/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the
-/// end.
-/// Each starting function will either return `false(0)` if the tree is collapsed
-/// or hidden and therefore does not need to be filled with content or `true(1)`
-/// if visible and required to be filled.
-///
-/// !!! Note
-/// The tree header does not require and layouting function and instead
-/// calculates a auto height based on the currently used font size
-///
-/// The tree ending functions only need to be called if the tree content is
-/// actually visible. So make sure the tree push function is guarded by `if`
-/// and the pop call is only taken if the tree is visible.

-/// ### Properties
-/// Properties are the main value modification widgets in Nuklear. Changing a value
-/// can be achieved by dragging, adding/removing incremental steps on button click
-/// or by directly typing a number.
-///
-/// #### Usage
-/// Each property requires a unique name for identifaction that is also used for
-/// displaying a label. If you want to use the same name multiple times make sure
-/// add a '#' before your name. The '#' will not be shown but will generate a
-/// unique ID. Each propery also takes in a minimum and maximum value. If you want
-/// to make use of the complete number range of a type just use the provided
-/// type limits from `limits.h`. For example `INT_MIN` and `INT_MAX` for
-/// `nk_property_int` and `nk_propertyi`. In additional each property takes in
-/// a increment value that will be added or subtracted if either the increment
-/// decrement button is clicked. Finally there is a value for increment per pixel
-/// dragged that is added or subtracted from the value.
-///

- * FONT
- *
- * ===============================================================*/
-/* Font handling in this library was designed to be quite customizable and lets
- you decide what you want to use and what you want to provide. There are three
- different ways to use the font atlas. The first two will use your font
- handling scheme and only requires essential data to run nuklear. The next
- slightly more advanced features is font handling with vertex buffer output.
- Finally the most complex API wise is using nuklear's font baking API.
-
- 1.) Using your own implementation without vertex buffer output
- --------------------------------------------------------------
- So first up the easiest way to do font handling is by just providing a
- `nk_user_font` struct which only requires the height in pixel of the used
- font and a callback to calculate the width of a string. This way of handling
- fonts is best fitted for using the normal draw shape command API where you
- do all the text drawing yourself and the library does not require any kind
- of deeper knowledge about which font handling mechanism you use.
- IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist
- over the complete life time! I know this sucks but it is currently the only
- way to switch between fonts.
-
- float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
- {
- your_font_type *type = handle.ptr;
- float text_width = ...;
- return text_width;
- }
-
- struct nk_user_font font;
- font.userdata.ptr = &your_font_class_or_struct;
- font.height = your_font_height;
- font.width = your_text_width_calculation;
-
- struct nk_context ctx;
- nk_init_default(&ctx, &font);
-
- 2.) Using your own implementation with vertex buffer output
- --------------------------------------------------------------
- While the first approach works fine if you don't want to use the optional
- vertex buffer output it is not enough if you do. To get font handling working
- for these cases you have to provide two additional parameters inside the
- `nk_user_font`. First a texture atlas handle used to draw text as subimages
- of a bigger font atlas texture and a callback to query a character's glyph
- information (offset, size, ...). So it is still possible to provide your own
- font and use the vertex buffer output.
-
- float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
- {
- your_font_type *type = handle.ptr;
- float text_width = ...;
- return text_width;
- }
- void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint)
- {
- your_font_type *type = handle.ptr;
- glyph.width = ...;
- glyph.height = ...;
- glyph.xadvance = ...;
- glyph.uv[0].x = ...;
- glyph.uv[0].y = ...;
- glyph.uv[1].x = ...;
- glyph.uv[1].y = ...;
- glyph.offset.x = ...;
- glyph.offset.y = ...;
- }
-
- struct nk_user_font font;
- font.userdata.ptr = &your_font_class_or_struct;
- font.height = your_font_height;
- font.width = your_text_width_calculation;
- font.query = query_your_font_glyph;
- font.texture.id = your_font_texture;
-
- struct nk_context ctx;
- nk_init_default(&ctx, &font);
-
- 3.) Nuklear font baker
- ------------------------------------
- The final approach if you do not have a font handling functionality or don't
- want to use it in this library is by using the optional font baker.
- The font baker APIs can be used to create a font plus font atlas texture
- and can be used with or without the vertex buffer output.
-
- It still uses the `nk_user_font` struct and the two different approaches
- previously stated still work. The font baker is not located inside
- `nk_context` like all other systems since it can be understood as more of
- an extension to nuklear and does not really depend on any `nk_context` state.
-
- Font baker need to be initialized first by one of the nk_font_atlas_init_xxx
- functions. If you don't care about memory just call the default version
- `nk_font_atlas_init_default` which will allocate all memory from the standard library.
- If you want to control memory allocation but you don't care if the allocated
- memory is temporary and therefore can be freed directly after the baking process
- is over or permanent you can call `nk_font_atlas_init`.
-
- After successfully initializing the font baker you can add Truetype(.ttf) fonts from
- different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`.
- functions. Adding font will permanently store each font, font config and ttf memory block(!)
- inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
- the font baker by for example adding additional fonts you can call
- `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end).
-
- As soon as you added all fonts you wanted you can now start the baking process
- for every selected glyph to image by calling `nk_font_atlas_bake`.
- The baking process returns image memory, width and height which can be used to
- either create your own image object or upload it to any graphics library.
- No matter which case you finally have to call `nk_font_atlas_end` which
- will free all temporary memory including the font atlas image so make sure
- you created our texture beforehand. `nk_font_atlas_end` requires a handle
- to your font texture or object and optionally fills a `struct nk_draw_null_texture`
- which can be used for the optional vertex output. If you don't want it just
- set the argument to `NULL`.
-
- At this point you are done and if you don't want to reuse the font atlas you
- can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration
- memory. Finally if you don't use the font atlas and any of it's fonts anymore
- you need to call `nk_font_atlas_clear` to free all memory still being used.
-
- struct nk_font_atlas atlas;
- nk_font_atlas_init_default(&atlas);
- nk_font_atlas_begin(&atlas);
- nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0);
- nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0);
- const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32);
- nk_font_atlas_end(&atlas, nk_handle_id(texture), 0);
-
- struct nk_context ctx;
- nk_init_default(&ctx, &font->handle);
- while (1) {
-
- }
- nk_font_atlas_clear(&atlas);
-
- The font baker API is probably the most complex API inside this library and
- I would suggest reading some of my examples `example/` to get a grip on how
- to use the font atlas. There are a number of details I left out. For example
- how to merge fonts, configure a font with `nk_font_config` to use other languages,
- use another texture coordinate format and a lot more:
-
- struct nk_font_config cfg = nk_font_config(font_pixel_height);
- cfg.merge_mode = nk_false or nk_true;
- cfg.range = nk_font_korean_glyph_ranges();
- cfg.coord_type = NK_COORD_PIXEL;
- nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

-/* ==============================================================

- * MEMORY BUFFER
- *
- * ===============================================================*/
-/* A basic (double)-buffer with linear allocation and resetting as only
- freeing policy. The buffer's main purpose is to control all memory management
- inside the GUI toolkit and still leave memory control as much as possible in
- the hand of the user while also making sure the library is easy to use if
- not as much control is needed.
- In general all memory inside this library can be provided from the user in
- three different ways.
-
- The first way and the one providing most control is by just passing a fixed
- size memory block. In this case all control lies in the hand of the user
- since he can exactly control where the memory comes from and how much memory
- the library should consume. Of course using the fixed size API removes the
- ability to automatically resize a buffer if not enough memory is provided so
- you have to take over the resizing. While being a fixed sized buffer sounds
- quite limiting, it is very effective in this library since the actual memory
- consumption is quite stable and has a fixed upper bound for a lot of cases.
-
- If you don't want to think about how much memory the library should allocate
- at all time or have a very dynamic UI with unpredictable memory consumption
- habits but still want control over memory allocation you can use the dynamic
- allocator based API. The allocator consists of two callbacks for allocating
- and freeing memory and optional userdata so you can plugin your own allocator.
-
- The final and easiest way can be used by defining
- NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory
- allocation functions malloc and free and takes over complete control over
- memory in this library.

- started. It is probably important to note that the command buffer is the main
- drawing API and the optional vertex buffer API only takes this format and
- converts it into a hardware accessible format.
-
- To use the command queue to draw your own widgets you can access the
- command buffer of each window by calling `nk_window_get_canvas` after
- previously having called `nk_begin`:
-
- void draw_red_rectangle_widget(struct nk_context *ctx)
- {
- struct nk_command_buffer *canvas;
- struct nk_input *input = &ctx->input;
- canvas = nk_window_get_canvas(ctx);
-
- struct nk_rect space;
- enum nk_widget_layout_states state;
- state = nk_widget(&space, ctx);
- if (!state) return;
-
- if (state != NK_WIDGET_ROM)
- update_your_widget_by_user_input(...);
- nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0));
- }
-
- if (nk_begin(...)) {
- nk_layout_row_dynamic(ctx, 25, 1);
- draw_red_rectangle_widget(ctx);
- }
- nk_end(..)
-
- Important to know if you want to create your own widgets is the `nk_widget`
- call. It allocates space on the panel reserved for this widget to be used,
- but also returns the state of the widget space. If your widget is not seen and does
- not have to be updated it is '0' and you can just return. If it only has
- to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both
- update and draw your widget. The reason for separating is to only draw and
- update what is actually necessary which is crucial for performance.
