Subject: [SDL] Mac OS X fullscreen and fades

If I were to make a patch that lets you set an environment variable to 
disable the fades when changing to/from fullscreen modes on OS X, would it 
be feasible to include in CVS?

I realize those fades are there to hide any flickering that might occur, 
but they're painfully long, especially when trying to change resolutions 
mid-game.

Fast Fade Patch

This is an improved version of Gregory's patch that adds a fast, asynchronous fade-through-black at every transition to or from a fullscreen mode, using Apple's fade API. It works well with my OpenGL app on 10.2, 10.3, and 10.4. It should work in 2D (non-OpenGL) mode too, but I only did minimal testing of that case.
(Here's the discussion on the mailing list, for the record: http://thread.gmane.org/gmane.comp.lib.sdl/25530 )

Tried it briefly here...fades faster, which is nice, and doesn't go back to the desktop when changing resolutions, which is nicer still.

If there are no objections, I'll apply this patch.
