*
* rl_gputex v1.1 - GPU compressed textures loading and saving
*
* DESCRIPTION:
*
* Load GPU compressed image data from image files provided as memory data arrays,
* data is loaded compressed, ready to be loaded into GPU
*
* Note that some file formats (DDS, PVR, KTX) also support uncompressed data storage.
* In those cases data is loaded uncompressed and format is returned
*
* FIXME: This library still depends on Raylib due to the following reasons:
* - rl_save_ktx_to_memory() requires rlGetGlTextureFormats() from rlgl.h
* though this is not a problem, if you don't need KTX support
*
* TODO:
* - Review rl_load_ktx_from_memory() to support KTX v2.2 specs
*
* CONFIGURATION:
*
* #define RL_GPUTEX_SUPPORT_DDS
* #define RL_GPUTEX_SUPPORT_PKM
* #define RL_GPUTEX_SUPPORT_KTX
* #define RL_GPUTEX_SUPPORT_PVR
* #define RL_GPUTEX_SUPPORT_ASTC
* Define desired file formats to be supported
*
* #define RL_GPUTEX_SHOW_LOG_INFO
* Define, if you wish to see warnings generated by the library
* This will include <stdio.h> unless you provide your own RL_GPUTEX_LOG
* #define RL_GPUTEX_LOG
* Define, if you wish to provide your own warning function
* Make sure that this macro puts newline character '\n' at the end
*
* #define RL_GPUTEX_MALLOC
* #define RL_GPUTEX_FREE
* Define those macros in order to provide your own libc-compliant allocator;
* not doing so will include <stdlib.h>
* If you're providing any of those, you must provide ALL of them,
* otherwise the code will (most likely) crash...
*
* #define RL_GPUTEX_NULL
* Define in order to provide your own libc-compliant NULL pointer;
* not doing so will include <stdlib.h>
*
* #define RL_GPUTEX_MEMCPY
* Define in order to provide your own libc-compliant 'memcpy' function;
* not doing so will include <string.h>
*
* #define RLGPUTEXAPI
* Define to compiler-specific intrinsic, if you wish to export public functions
* There is no need to do so when statically linking
*
* VERSIONS HISTORY:
* 1.1 (15-Jul-2025) Several minor fixes related to specific image formats; some work has been done
* in order to decouple the library from Raylib by introducing few new macros; library still
* requires Raylib in order to function properly
*
* 1.0 (17-Sep-2022) First version has been created by migrating part of compressed-texture-loading
* functionality from Raylib src/rtextures.c into self-contained library
