RaylibSIMD

Toy re-implementations of some of the software image routines in Raylib using the SSE instruction set for my learning purposes.

To test it out, copy RaylibSIMD.h into Raylib's folder and in textures.c after all the file includes, include and enable the single header file.

#define RAYLIB_SIMD_IMPLEMENTATION
#include "RaylibSIMD.h"
