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.

37 - Avoid erasing window on minimize, or disable minimize 37 - Fix white OpenGL window on minimize
38 - Find out what events should be sent/ignored if window is mimimized
39 - Find a better way to deal with resolution/depth switch while app is running
40 - Resizeable windows
41 - Check accuracy of QZ_SetGamma()
38 Problems: 42 Problems:
39 - OGL not working in full screen with software renderer 43 - OGL not working in full screen with software renderer
40 - SetColors sets palette correctly but clears framebuffer 44 - SetColors sets palette correctly but clears framebuffer
41 - Crash in CG after several mode switches 45 - Crash in CG after several mode switches
42 - Retained windows don't draw their title bar quite right (OS Bug) 46 - Retained windows don't draw their title bar quite right (OS Bug) (not using retained windows)
43 - Should I do depth switching for windowed modes? - No, not usually. 47 - Cursor in 8 bit modes is screwy (might just be Radeon PCI bug)
44 - Launch times are slow, maybe prebinding will help 48 - Warping cursor delays mouse events for a fraction of a second,
45 - Direct framebuffer access has some artifacts, maybe a driver issue 49 there is a hack around this that helps a bit
46 - Cursor in 8 bit modes is screwy
