Create xorg native RenderWindow to display a pixel buffer directly from vram in a window without SDL #6

reading the pixelbuffer from vram into ram, just to dump it back into vram via sdl immediately, every single frame, is really ass. also requires input handling:

get mouse position
get mouse delta
hide cursor
lock cursor
mouse buttons (down,up)
keyboard buttons (down,up)

done some research: this REQUIRES opengl! we should still not ditch SDL2, because SDL2 enables us to do easy audio output, and input handling... so... with this, our total requirement list would be opencl, opengl, and sdl2...
