Improvements from Alfred:

- Add new SDL_WINDOW_FULLSCREEN_DESKTOP video mode, makes a fullscreen window the size of the desktop (i.e no window manager mode change)
- Fix crash in warp mouse if you specified null as the window
- Added new SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS Hint, if set to 0 then don't minimize a fullscreen window on focus lost (if not set or set to non-zero then minimize on focus loss)
