Subject: SDL Quartz video update

-better mouse motion events
-fixed minification bugs (except OpenGL)
-fixed QZ_SetGamma for correct semantics
-fade/unfade display before/after rez switch
-experimental obscured-check/blind-copy code

The obscured code, while it speeds up window drawing substantially, isn't
ready yet. The reason is that there doesn't (yet) seem to be a way to know
when the window is dragged or when the window suddenly comes to the
foreground. Since Carbon windows seem to allow detection of such things, I
suspect it is possible through some window server API. Cocoa(NSWindow) has no
functions for such things, AFAIK.
