#define RGFW_OSMESA - (optional) use OSmesa as backend (instead of system's opengl api + regular opengl)
#define RGFW_BUFFER - (optional) just draw directly to (RGFW) window pixel buffer that is drawn to screen (the buffer is in the RGBA format)

This version doesn't work for desktops (I'm pretty sure)

#define RGFW_DIRECTX - (optional) use directX for the rendering backend (rather than opengl) (windows only, defaults to opengl for unix)
#define RGFW_NO_API - (optional) don't use any rendering API (no opengl, no vulkan, no directX)
#define RGFW_LINK_EGL (optional) (windows only) if EGL is being used, if EGL functions should be defined dymanically (using GetProcAddress)

#define RGFW_NO_X11_CURSOR_PRELOAD (optional) (unix only) Use XCursor, but don't link it in code, (you'll have to link it with -lXcursor)
#define RGFW_NO_DPI - Do not include calculate DPI (no XRM nor libShcore included)
#define RGFW_ALLOC_DROPFILES (optional) if room should be allocating for drop files (by default it's global data)
#define RGFW_MALLOC x - choose what function to use to allocate, by default the standard malloc is used
#define RGFW_CALLOC x - choose what function to use to allocate (calloc), by default the standard calloc is used

#define RGFW_EXPORT - Use when building RGFW
#define RGFW_IMPORT - Use when linking with RGFW (not as a single-header)

Credits :
EimaMei/Sacode : Much of the code for creating windows using winapi, Wrote the Silicon library, helped with MacOS Support, siliapp.h -> referencing
stb - This project is heavily inspired by the stb single header files
GLFW:
certain parts of winapi and X11 are very poorly documented,
GLFW's source code was referenced and used throughout the project (used code is marked in some way),
this mainly includes, code for drag and drops, code for setting the icon to a bitmap and the code for managing the clipboard for X11 (as these parts are not documented very well)
