Date: Sat, 19 Jan 2002 17:24:32 -0500 (EST) From: Darrell Walisser <dwaliss1@purdue.edu> 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.
