The short version is that mouse-tracking events are generated when the
mouse enters or leaves a "tracking area" (10.5) or "tracking rect"
(earlier systems) which requires some work to set up and possibly some
work to maintain but potentially offers greater flexibility than
"mouse entered/left view" would.
