OpenGL: Fix crash on start with Mesa drivers 

glFramebufferTexture() is only available from OGL 3.2, it is also not part of the ARB_framebuffer_object extension.
I don't know if there is a better way to check for mesa drivers or if using the 2D version will have issues with f2f16a256, but so far I had no problems
