- * The master copy of khrplatform.h is maintained in the Khronos EGL
- * Registry repository at https://github.com/KhronosGroup/EGL-Registry
- * The last semantic modification to khrplatform.h was at commit ID:
- *      67a3e0864c2d75ea5287b9f3d2eb74a745936692
- *
- * Adopters may modify this file to suit their platform. Adopters are
- * encouraged to submit platform specific modifications to the Khronos
- * group so that they can be included in future versions of this file.
- * Please submit changes by filing pull requests or issues on
- * the EGL Registry repository linked above.
- *
- *
- * See the Implementer's Guidelines for information about where this file
- * should be located on your system and for more details of its use:
- *    http://www.khronos.org/registry/implementers_guide.pdf
- *
- * This file should be included as
- *        #include <KHR/khrplatform.h>
- * by Khronos client API header files that use its types and defines.
- *
- * The types in khrplatform.h should only be used to define API-specific types.
- *
- * Types defined in khrplatform.h:
- *    khronos_int8_t              signed   8  bit
- *    khronos_uint8_t             unsigned 8  bit
- *    khronos_int16_t             signed   16 bit
- *    khronos_uint16_t            unsigned 16 bit
- *    khronos_int32_t             signed   32 bit
- *    khronos_uint32_t            unsigned 32 bit
- *    khronos_int64_t             signed   64 bit
- *    khronos_uint64_t            unsigned 64 bit
- *    khronos_intptr_t            signed   same number of bits as a pointer
- *    khronos_uintptr_t           unsigned same number of bits as a pointer
- *    khronos_ssize_t             signed   size
- *    khronos_usize_t             unsigned size
- *    khronos_float_t             signed   32 bit floating point
- *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
- *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
- *                                         nanoseconds
- *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
- *    khronos_boolean_enum_t      enumerated boolean type. This should
- *      only be used as a base type when a client API's boolean type is
- *      an enum. Client APIs which use an integer or other type for
- *      booleans cannot use this as the base type for their boolean.
- *
- * Tokens defined in khrplatform.h:
- *
- *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
- *
- *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
- *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
- *
- * Calling convention macros defined in this file:
- *    KHRONOS_APICALL
- *    KHRONOS_APIENTRY
- *    KHRONOS_APIATTRIBUTES
- *
- * These may be used in function prototypes as:

-# S3TC DXT1/DXT5 Texture Decompression
-
-This is the reposting of some S3TC DXT texture decompression routines that I wrote and published to an old blog in 2009.
-
-## Why republish?
-
-I hadn't thought about these routines in a very long time, but I recently discovered my name in some Amazon Fire copyright notices and traced the notice back to these routines, or a derivative thereof, being include in [ffmpeg](https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/texturedsp.c), which I thought was pretty nifty. Completely coincidentally, the very next day I received an email asking about these very same routines. I figured that was a sign that I should share these routines again via a more modern mechanism.
-
-## (Dual) License
-
-When using these routines, feel free to chose one of either:
-
-* My original worded "license" (which was intended to be essentially public domain).
-* The MIT license 
-
-My original worded "license" was intended to be extremely permissive and does not require attribution. However, given it is highly non-standard (not checked over by a lawyer) then that may lead to ambiguity. If you need something a bit more solid then the MIT license ought to meet your needs.
-
-## Original Blog Post
-
-_October 21st, 2009_
-
-> Earlier this year I offered to write the [S3TC](http://en.wikipedia.org/wiki/S3_Texture_Compression) decompression routines that allowed texture exporting functionality to be included in the ‘Collada Exporter’ plug-in for the [C4 Engine](http://www.terathon.com/c4engine/index.php). After doing a bit of research I was pointed towards the [perfect resource](http://www.opengl.org/registry/specs/EXT/texture_compression_s3tc.txt) by C4’s creator, Eric Lengyel. Any information I’d found prior to this made the process sound a bit convoluted but after looking over the reference I was able to write the decompression routines with relative ease.
-> 
-> I basically forgot about these routines until a couple of days ago when the question of how to decompress S3TC (specifically DXT1 and DXT5) textures was brought up on the [XNA Creators Club](http://creators.xna.com/) forums. As a result I’ve decided to release the methods that I wrote. In order to ensure the code compiled fine in any project I’ve removed all the C4 specific data-types and methods, and I’ve made no use of any methods that aren’t included. As a result things became a little messier, hopefully the code is still understandable. Without further ado here are my C++ methods to decompress DXT1 and DXT5 textures:
-> 
-> I’m still in the midst of writing an entry on iPhone, ASP .NET, Linux and Mono so if you’re at all interested check back here in a few days.

-   before you include this file in *one* C or C++ file to create the implementation.

-   #include ...
-   #define STB_IMAGE_IMPLEMENTATION
-   #include "stb_image.h"
-
-   You can #define STBI_ASSERT(x) before the #include to avoid using assert.h.

-#define STBI_INCLUDE_STB_IMAGE_H
-
-// DOCUMENTATION
-//
-// Limitations:
-//    - no 12-bit-per-channel JPEG
-//    - no JPEGs with arithmetic coding
-//    - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-//    int x,y,n;
-//    unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-//    // ... process data if not NULL ...
-//    // ... x = width, y = height, n = # 8-bit components per pixel ...
-//    // ... replace '0' with '1'..'4' to force that many components per pixel
-//    // ... but 'n' will always be the number that it would have been if you said 0
-//    stbi_image_free(data);
-//
-// Standard parameters:
-//    int *x                 -- outputs image width in pixels
-//    int *y                 -- outputs image height in pixels
-//    int *channels_in_file  -- outputs # of image components in image file
-//    int desired_channels   -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
-// with each pixel consisting of N interleaved 8-bit components; the first
-// pixel pointed to is top-left-most in the image. There is no padding between
-// image scanlines or between pixels, regardless of format. The number of
-// components N is 'desired_channels' if desired_channels is non-zero, or
-// *channels_in_file otherwise. If desired_channels is non-zero,
-// *channels_in_file has the number of components that _would_ have been
-// output otherwise. E.g. if you set desired_channels to 4, you will always
-// get RGBA output, but you can check *channels_in_file to see if it's trivially
-// opaque because e.g. there were only 3 channels in the source image.
-//
-// An output image with N components has the following components interleaved
-// in this order in each pixel:
-//
-//     N=#comp     components
-//       1           grey
-//       2           grey, alpha
-//       3           red, green, blue
-//       4           red, green, blue, alpha
-//
-// If image loading fails for any reason, the return value will be NULL,
-// and *x, *y, *channels_in_file will be unchanged. The function
-// stbi_failure_reason() can be queried for an extremely brief, end-user
-// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
-// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
-// more user-friendly ones.
-//
-// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
-//
-// To query the width, height and component count of an image without having to
-// decode the full file, you can use the stbi_info family of functions:
-//
-//   int x,y,n,ok;
-//   ok = stbi_info(filename, &x, &y, &n);
-//   // returns ok=1 and sets x, y, n if image is a supported format,
-//   // 0 otherwise.
-//
-// Note that stb_image pervasively uses ints in its public API for sizes,
-// including sizes of memory buffers. This is now part of the API and thus
-// hard to change without causing breakage. As a result, the various image
-// loaders all have certain limits on image size; these differ somewhat
-// by format but generally boil down to either just under 2GB or just under
-// 1GB. When the decoded image would be larger than this, stb_image decoding
-// will fail.
-//
-// Additionally, stb_image will reject image files that have any of their
-// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS,
-// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit,
-// the only way to have an image with such dimensions load correctly
-// is for it to have a rather extreme aspect ratio. Either way, the
-// assumption here is that such larger images are likely to be malformed
-// or malicious. If you do need to load an image with individual dimensions
-// larger than that, and it still fits in the overall size limit, you can
-// #define STBI_MAX_DIMENSIONS on your own to be something larger.
-//
-// ===========================================================================
-//
-// UNICODE:
-//
-//   If compiling for Windows and you wish to use Unicode filenames, compile
-//   with
-//       #define STBI_WINDOWS_UTF8
-//   and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
-//   Windows wchar_t filenames to utf8.
-//
-// ===========================================================================
-//
-// Philosophy
-//
-// stb libraries are designed with the following priorities:
-//
-//    1. easy to use
-//    2. easy to maintain
-//    3. good performance
-//
-// Sometimes I let "good performance" creep up in priority over "easy to maintain",
-// and for best performance I may provide less-easy-to-use APIs that give higher
-// performance, in addition to the easy-to-use ones. Nevertheless, it's important
-// to keep in mind that from the standpoint of you, a client of this library,
-// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
-//
-// Some secondary priorities arise directly from the first two, some of which
-// provide more explicit reasons why performance can't be emphasized.
-//
-//    - Portable ("ease of use")
-//    - Small source code footprint ("easy to maintain")
-//    - No dependencies ("ease of use")
-//
-// ===========================================================================
-//
-// I/O callbacks
-//
-// I/O callbacks allow you to read from arbitrary sources, like packaged
-// files or some other source. Data read from callbacks are processed
-// through a small internal buffer (currently 128 bytes) to try to reduce
-// overhead.
-//
-// The three functions you must define are "read" (reads some bytes of data),
-// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
-//
-// ===========================================================================
-//
-// SIMD support
-//
-// The JPEG decoder will try to automatically use SIMD kernels on x86 when
-// supported by the compiler. For ARM Neon support, you must explicitly
-// request it.
-//
-// (The old do-it-yourself SIMD API is no longer supported in the current
-// code.)
-//
-// On x86, SSE2 will automatically be used when available based on a run-time
-// test; if not, the generic C versions are used as a fall-back. On ARM targets,
-// the typical path is to have separate builds for NEON and non-NEON devices
-// (at least this is true for iOS and Android). Therefore, the NEON support is
-// toggled by a build flag: define STBI_NEON to get NEON loops.
-//
-// If for some reason you do not want to use any of SIMD code, or if
-// you have issues compiling it, you can disable it entirely by
-// defining STBI_NO_SIMD.
-//
-// ===========================================================================
-//
-// HDR image support   (disable by defining STBI_NO_HDR)
-//
-// stb_image supports loading HDR images in general, and currently the Radiance
-// .HDR file format specifically. You can still load any file through the existing
-// interface; if you attempt to load an HDR file, it will be automatically remapped
-// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
-// both of these constants can be reconfigured through this interface:
-//
-//     stbi_hdr_to_ldr_gamma(2.2f);
-//     stbi_hdr_to_ldr_scale(1.0f);
-//
-// (note, do not use _inverse_ constants; stbi_image will invert them
-// appropriately).
-//
-// Additionally, there is a new, parallel interface for loading files as
-// (linear) floats to preserve the full dynamic range:
-//
-//    float *data = stbi_loadf(filename, &x, &y, &n, 0);
-//
-// If you load LDR images through this interface, those images will
-// be promoted to floating point values, run through the inverse of
-// constants corresponding to the above:
-//
-//     stbi_ldr_to_hdr_scale(1.0f);
-//     stbi_ldr_to_hdr_gamma(2.2f);
-//
-// Finally, given a filename (or an open file or memory block--see header
-// file for details) containing image data, you can query for the "most
-// appropriate" interface to use (that is, whether the image is HDR or
-// not), using:
-//
-//     stbi_is_hdr(char *filename);
-//
-// ===========================================================================
-//
-// iPhone PNG support:
-//
-// We optionally support converting iPhone-formatted PNGs (which store
-// premultiplied BGRA) back to RGB, even though they're internally encoded
-// differently. To enable this conversion, call
-// stbi_convert_iphone_png_to_rgb(1).
-//
-// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
-// pixel to remove any premultiplied alpha *only* if the image file explicitly
-// says there's premultiplied data (currently only happens in iPhone images,
-// and only if iPhone convert-to-rgb processing is on).
-//
-// ===========================================================================
-//
-// ADDITIONAL CONFIGURATION
-//
-//  - You can suppress implementation of any of the decoders to reduce
-//    your code footprint by #defining one or more of the following
-//    symbols before creating the implementation.
-//
-//        STBI_NO_JPEG
-//        STBI_NO_PNG
-//        STBI_NO_BMP
-//        STBI_NO_PSD
-//        STBI_NO_TGA
-//        STBI_NO_GIF
-//        STBI_NO_HDR
-//        STBI_NO_PIC
-//        STBI_NO_PNM   (.ppm and .pgm)
-//
-//  - You can request *only* certain decoders and suppress all other ones
-//    (this will be more forward-compatible, as addition of new decoders
-//    doesn't require you to disable them explicitly):
-//
-//        STBI_ONLY_JPEG
-//        STBI_ONLY_PNG
-//        STBI_ONLY_BMP
-//        STBI_ONLY_PSD
-//        STBI_ONLY_TGA
-//        STBI_ONLY_GIF
-//        STBI_ONLY_HDR
-//        STBI_ONLY_PIC
-//        STBI_ONLY_PNM   (.ppm and .pgm)
-//
-//   - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
-//     want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB
-//
-//  - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater
-//    than that size (in either width or height) without further processing.
-//    This is to let programs in the wild set an upper bound to prevent
-//    denial-of-service attacks on untrusted data, as one could generate a
-//    valid image of gigantic dimensions and force stb_image to allocate a
-//    huge block of memory and spend disproportionate time decoding it. By
-//    default this is set to (1 << 24), which is 16777216, but that's still
-//    very big.

-//    simple implementation
-//      - only 8-bit samples
-//      - no CRC checking
-//      - allocates lots of intermediate memory
-//        - avoids problem of streaming data between subsystems
-//        - avoids explicit window management
-//    performance
-//      - uses stb_zlib, a PD zlib implementation with fast huffman decoding

-/* stb_image_write - v1.16 - public domain - http://nothings.org/stb
-   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
-                                     no warranty implied; use at your own risk
-
-   Before #including,
-
-       #define STB_IMAGE_WRITE_IMPLEMENTATION
-
-   in the file that you want to have the implementation.
-
-   Will probably not work correctly with strict-aliasing optimizations.
-
-ABOUT:
-
-   This header file is a library for writing images to C stdio or a callback.
-
-   The PNG output is not optimal; it is 20-50% larger than the file
-   written by a decent optimizing implementation; though providing a custom
-   zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
-   This library is designed for source code compactness and simplicity,
-   not optimal image file size or run-time performance.
-
-BUILDING:
-
-   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
-   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
-   malloc,realloc,free.
-   You can #define STBIW_MEMMOVE() to replace memmove()
-   You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
-   for PNG compression (instead of the builtin one), it must have the following signature:
-   unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
-   The returned data will be freed with STBIW_FREE() (free() by default),
-   so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
-
-UNICODE:
-
-   If compiling for Windows and you wish to use Unicode filenames, compile
-   with
-       #define STBIW_WINDOWS_UTF8
-   and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
-   Windows wchar_t filenames to utf8.
-
-USAGE:
-
-   There are five functions, one for each image file format:
-
-     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
-     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
-     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
-
-     void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
-
-   There are also five equivalent functions that use an arbitrary write function. You are
-   expected to open/close your file-equivalent before and after calling these:
-
-     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
-     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
-     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
-
-   where the callback is:
-      void stbi_write_func(void *context, void *data, int size);
-
-   You can configure it with these global variables:
-      int stbi_write_tga_with_rle;             // defaults to true; set to 0 to disable RLE
-      int stbi_write_png_compression_level;    // defaults to 8; set to higher for more compression
-      int stbi_write_force_png_filter;         // defaults to -1; set to 0..5 to force a filter mode
-
-
-   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
-   functions, so the library will not use stdio.h at all. However, this will
-   also disable HDR writing, because it requires stdio for formatted output.
-
-   Each function returns 0 on failure and non-0 on success.
-
-   The functions create an image file defined by the parameters. The image
-   is a rectangle of pixels stored from left-to-right, top-to-bottom.
-   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
-   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
-   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
-   The *data pointer points to the first byte of the top-left-most pixel.
-   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
-   a row of pixels to the first byte of the next row of pixels.
-
-   PNG creates output files with the same number of components as the input.
-   The BMP format expands Y to RGB in the file format and does not
-   output alpha.
-
-   PNG supports writing rectangles of data even when the bytes storing rows of
-   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
-   by supplying the stride between the beginning of adjacent rows. The other
-   formats do not. (Thus you cannot write a native-format BMP through the BMP
-   writer, both because it is in BGR order and because it may have padding
-   at the end of the line.)
-
-   PNG allows you to set the deflate compression level by setting the global
-   variable 'stbi_write_png_compression_level' (it defaults to 8).
-
-   HDR expects linear float data. Since the format is always 32-bit rgb(e)
-   data, alpha (if provided) is discarded, and for monochrome data it is
-   replicated across all three channels.
-
-   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
-   data, set the global variable 'stbi_write_tga_with_rle' to 0.
-
-   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
-   Higher quality looks better but results in a bigger image.
-   JPEG baseline (no JPEG progressive).
