protected Cursor calculateCursor()

public void commitDrag()
DragTracker
SelectionTool
supports keyboard accessible drags. In such scenarios
it is up to the SelectionTool to interpret commit and abort keystrokes.
Since the DragTracker cannot do this, this method is used to indicate that the User
has committed the drag using the keyboard. Abort is not handled specially, and the
DragTracker should peform the usual cleanup in its Tool.deactivate()
method.
