~ Initial SDL2 implementation
Limitation - Dependent projects need to set NAZARA_PLATFORM_SDL2 if nazara has been build with SDL2 since OpenGL.hpp (and maybe some other headers) exposes platform details - SDL2 window doesn't supports async window since the API isn't fitting for now - Contexts parameters can't be changed until we close all the SDL windows (SDL limitation)
