 Document passes in the correct Cartesian coordinates being pointed to by the mouse.
 So all we have to be concerned with is properly scaling our hot zones/handle sizes,
 since we generally *don't* want those to scale with the zoom level. ;-)

+What is going on here?
+If we're zoomed out to, say, 50%, & our radius is 10.0 (absolute), then on screen
