/*
HOW TO USE:
In exactly one translation unit (.c or .cpp file), #define MSF_GIF_IMPL before including the header, like so:
#define MSF_GIF_IMPL
#include "msf_gif.h"
Everywhere else, just include the header like normal.
USAGE EXAMPLE:
int width = 480, height = 320, centisecondsPerFrame = 5, bitDepth = 16;
MsfGifState gifState = {};

Detailed function documentation can be found in the header section below.
REPLACING MALLOC:
This library uses malloc+realloc+free internally for memory allocation.
To facilitate integration with custom memory allocators, these calls go through macros, which can be redefined.
The expected function signature equivalents of the macros are as follows:
void * MSF_GIF_MALLOC(void * context, size_t newSize)
void * MSF_GIF_REALLOC(void * context, void * oldMemory, size_t oldSize, size_t newSize)
void MSF_GIF_FREE(void * context, void * oldMemory, size_t oldSize)
If your allocator needs a context pointer, you can set the `customAllocatorContext` field of the MsfGifState struct
before calling msf_gif_begin(), and it will be passed to all subsequent allocator macro calls.
See end of file for license information.

*
* rgif.h v0.5
*
* Original implementation (gif.h) by Charlie Tangora [ctangora -at- gmail -dot- com]
* adapted to C99, reformatted and renamed by Ramon Santamaria (@raysan5)
*
* This file offers a simple, very limited way to create animated GIFs directly in code.
*
* Those looking for particular cleverness are likely to be disappointed; it's pretty
* much a straight-ahead implementation of the GIF format with optional Floyd-Steinberg
* dithering. (It does at least use delta encoding - only the changed portions of each
* frame are saved.)
*
* So resulting files are often quite large. The hope is that it will be handy nonetheless
* as a quick and easily-integrated way for programs to spit out animations.
*
* Only RGBA8 is currently supported as an input format. (The alpha is ignored.)
*
* CONFIGURATION:
*
* #define RGIF_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* USAGE:
* 1) Create a GifWriter struct. Pass it to GifBegin() to initialize and write the header.
* 2) Pass subsequent frames to GifWriteFrame().
* 3) Finally, call GifEnd() to close the file handle and free memory.

# Small Deflate
`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
which implements the Deflate (RFC 1951) compressed data format specification standard.
It is mainly tuned to get as much speed and compression ratio from as little code
as needed to keep the implementation as concise as possible.
## Features
- Portable single header and source file duo written in ANSI C (ISO C90)
- Dual license with either MIT or public domain
- Small implementation
- Deflate: 525 LoC
- Inflate: 320 LoC
- Webassembly:
- Deflate ~3.7 KB (~2.2KB compressed)
- Inflate ~3.6 KB (~2.2KB compressed)
## Usage:
This file behaves differently depending on what symbols you define
before including it.
Header-File mode:
If you do not define `SDEFL_IMPLEMENTATION` before including this file, it
will operate in header only mode. In this mode it declares all used structs
and the API of the library without including the implementation of the library.
Implementation mode:
If you define `SDEFL_IMPLEMENTATION` before including this file, it will
compile the implementation . Make sure that you only include
this file implementation in *one* C or C++ file to prevent collisions.

# Small Deflate
`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
which implements the Deflate (RFC 1951) compressed data format specification standard.
It is mainly tuned to get as much speed and compression ratio from as little code
as needed to keep the implementation as concise as possible.
## Features
- Portable single header and source file duo written in ANSI C (ISO C90)
- Dual license with either MIT or public domain
- Small implementation
- Deflate: 525 LoC
- Inflate: 320 LoC
- Webassembly:
- Deflate ~3.7 KB (~2.2KB compressed)
- Inflate ~3.6 KB (~2.2KB compressed)
## Usage:
This file behaves differently depending on what symbols you define
before including it.
Header-File mode:
If you do not define `SINFL_IMPLEMENTATION` before including this file, it
will operate in header only mode. In this mode it declares all used structs
and the API of the library without including the implementation of the library.
Implementation mode:
If you define `SINFL_IMPLEMENTATION` before including this file, it will
compile the implementation. Make sure that you only include
this file implementation in *one* C or C++ file to prevent collisions.
