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

Problems:

- OGL not working in full screen with software renderer

- SetColors sets palette correctly but clears framebuffer

- Warping cursor delays mouse events for a fraction of a second,

there is a hack around this that helps a bit
