SDL_SetWindowSize limits to desktop resolution, SDL_CreateWindow doesn't.

Oh, interesting...SDL_CreateWindow() will let you make a window larger than the desktop, but SDL_SetWindowSize won't.

This was on X11, don't know if that matters yet.

Decide which of these two API calls is correct.

I think originally both calls limited window size to desktop resolution, and we removed this limitation in CreateWindow but forgot SetWindowSize. I think there might be some tap dancing needed to make that work on all platforms.
