+    
+    @abstract SDL video driver for MacOS X.
+    
+    @discussion
+    
+    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
+        - Set the window icon (dock icon when API is available)
+        - Avoid erasing window on minimize, or disable minimize
+    Problems:
+        - OGL not working in full screen with software renderer
+        - SetColors sets palette correctly but clears framebuffer
+        - Crash in CG after several mode switches
+        - Retained windows don't draw their title bar quite right (OS Bug)
+        - Should I do depth switching for windowed modes?
+        - Launch times are slow, maybe prebinding will help
+        - Direct framebuffer access has some artifacts, maybe a driver issue
+        - Cursor in 8 bit modes is screwy
+        - Modifier + mouse-down maps alternate mouse button, but if modifier is released
+           before mouse button, corresponding mouse-up event is not generated.
+        - Clicking in content activates app, but doesn't generate the activate event,
+          and subsequent switches generate no activate/deactivate events! (OS Bug I hope)
