TODO
- Hardware Cursor support with NSCursor instead of Carbon
- Keyboard repeat/mouse speed adjust (if needed)
- Multiple monitor support (currently only main display)
- Accelerated blitting support
- Fix white OpenGL window on minimize (fixed) (update: broken again on 10.2)
- Find out what events should be sent/ignored if window is minimized
- Find a way to deal with external resolution/depth switch while app is running
- 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 (I think this has been fixed)
- 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) (update: not just Radeon)
- Warping cursor delays mouse events for a fraction of a second,
there is a hack around this that helps a bit
