mouse moves into and out of your window; this would usually be done
using a mouse tracking region (HIViewNewTrackingArea) or a
kEventMouseMoved or kEventWindowCursorChange Carbon event.
There is also currently no undeprecated Carbon API for creating a
custom cursor. We plan to add Carbon API for this task in Leopard.
Until then, we recommend using either the deprecated Quickdraw API,
Do not post admin requests to the list. They will be ignored.
