31 TODO
32 - Hardware Cursor support with NSCursor instead of Carbon
33 - Keyboard repeat/mouse speed adjust (if needed)
34 - Multiple monitor support (currently only main display)
35 - Accelerated blitting support
36 - Set the window icon (dock icon when API is available)
37 - Avoid erasing window on minimize, or disable minimize
38 Problems:
39 - OGL not working in full screen with software renderer
40 - SetColors sets palette correctly but clears framebuffer
41 - Crash in CG after several mode switches
42 - Retained windows don't draw their title bar quite right (OS Bug)
43 - Should I do depth switching for windowed modes?
44 - Launch times are slow, maybe prebinding will help
45 - Direct framebuffer access has some artifacts, maybe a driver issue
46 - Cursor in 8 bit modes is screwy
47 - Modifier + mouse-down maps alternate mouse button, but if modifier is released
48 before mouse button, corresponding mouse-up event is not generated.
49 - Clicking in content activates app, but doesn't generate the activate event,
50 and subsequent switches generate no activate/deactivate events! (OS Bug I hope)
