After using setMouseCursor, I noticed that when the cursor leaves the window and re-enters, it returns to the default arrow cursor.
The solutions to this are to use either addCursorRect:cursor: or NSTrackingArea to ensure the cursor is set back to the preferred image. This implementation builds on the existing tracking area, which I think is better than an implementation using cursor rects.
Also, this patch includes a small modification to the dashboard example which allows you to click to the mouse cursor panel to keep the current cursor set until another element sets it back. As a result, the effect of this patch can be clearly seen.
