diff src/video/quartz/SDL_QuartzVideo.h @ 272:d1447a846d80

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.

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