32		* - Force relative mode in Grab mode even if SDL provides absolute coordinates?
33		* - Fullscreen mode
34		* - Gamma tables support is likely to be broken here
35	+	* - Events processing is bound to the general emulation thread as SDL requires
36	+	* to PumpEvents() within the same thread as the one that called SetVideoMode().
37	+	* Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
38	+	* - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
39	+	* - Backport hw cursor acceleration to Basilisk II?
