i think this would be best. it simplifies the game side (randr code totally
gone) and hands control to the de. if the de has a policy of "only alow native
resolutions" it will query randr, find the native screen resolutions and just
list those. user prefs apply to all games now nicely. hell if de wanted to it
could offer the user to explicitly select his desired fullscreen resolutions
once for all games and this ends up as some subset of available resolutions.
the user could even configure which screen fullscreen windows are to appear on
"always" etc. (your primary screen may not be screen id # 0 which many games
currently seems to just assume is my main monitor :)).
