| 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 |
