/*
 * A small header-only library to load an image into a RGB(A) SDL_Surface*,
 * like a stripped down version of SDL_Image, but using stb_image.h to decode
 * images and thus without any further external dependencies.
 * Supports all filetypes supported by stb_image (JPEG, PNG, TGA, BMP, PSD, ...
 * See stb_image.h for details).
 *
 * (C) 2015-2021 Daniel Gibson
 *
 * Homepage: https://github.com/DanielGibson/Snippets/
 *
 * Dependencies:
 *     libSDL2      http://www.libsdl.org
 *     stb_image.h  https://github.com/nothings/stb
 *
 * Usage:
 *   Put this file and stb_image.h somewhere in your project.
 *   In *one* of your .c/.cpp files, do
 *     #define SDL_STBIMAGE_IMPLEMENTATION
 *     #include "SDL_stbimage.h"
 *   to create the implementation of this library in that file.
 *   You can just #include "SDL_stbimage.h" (without the #define) in other source
 *   files to use it there. (See also below this comment for an usage example)
 *   This header implicitly #includes <SDL.h> and "stb_image.h".
 *
 *   You can #define SDL_STBIMG_DEF before including this header if you want to
 *   prepend anything to the function signatures (like "static", "inline",
 *   "__declspec(dllexport)", ...)
 *     Example: #define SDL_STBIMG_DEF static inline
 *
 *   By default, this deactivates stb_image's load from file functions via
 *   #define STBI_NO_STDIO, as they use stdio.h  and that adds a dependency to the
 *   CRT on windows and with SDL you're better off using SDL_RWops, incl. SDL_RWFromFile()
 *   If you wanna use stbi_load(), stbi_info(), stbi_load_from_file() etc anyway, do
 *     #define SDL_STBIMG_ALLOW_STDIO
 *   before including this header.
 *   (Note that all the STBIMG_* functions of this lib will work without it)
 *
 *   stb_image.h uses assert.h by default. You can #define STBI_ASSERT(x)
 *   before the implementation-#include of SDL_stbimage.h to avoid that.
 *   By default stb_image supports HDR images, for that it needs pow() from libm.
 *   If you don't need HDR (it can't be loaded into a SDL_Surface anyway),
 *   #define STBI_NO_LINEAR and #define STBI_NO_HDR before including this header.
 *

 *   This software is dual-licensed to the public domain and under the following
 *   license: you are granted a perpetual, irrevocable license to copy, modify,
 *   publish, and distribute this file as you see fit.
 *   No warranty implied; use at your own risk.
