32 TODO
33 - Hardware Cursor support with NSCursor instead of Carbon
34 - Keyboard repeat/mouse speed adjust (if needed)
35 - Multiple monitor support (currently only main display)
36 - Accelerated blitting support
37 - Fix white OpenGL window on minimize (fixed) (update: broken again on 10.2)
38 - Find out what events should be sent/ignored if window is minimized
39 - Find a way to deal with external resolution/depth switch while app is running
40 - Check accuracy of QZ_SetGamma()
41 Problems:
42 - OGL not working in full screen with software renderer
43 - SetColors sets palette correctly but clears framebuffer
44 - Crash in CG after several mode switches (I think this has been fixed)
45 - Retained windows don't draw their title bar quite right (OS Bug) (not using retained windows)
46 - Cursor in 8 bit modes is screwy (might just be Radeon PCI bug) (update: not just Radeon)
47 - Warping cursor delays mouse events for a fraction of a second,
48 there is a hack around this that helps a bit
