the PRIMARY PLANE and CRTC to scale as we please. But we need that SDL
has knowledge of the video modes we are going to use for fullscreen
window sizes, even if we are faking their use. If not, SDL only considers
the in-use video mode as available, and sets every window to that size
before we get to CreateWindow or ReconfigureWindow. */
