Continually polling the mouse location in a repeat loop uses up a lot of
system resources. In MacOS (before OS X) it wasn't as big a deal because
the Mac didn't really multitask and so you weren't holding up any other
apps very much by hogging the event queue with a long repeat loop. But
on all other OSs, tying up the event queue with non-stop polling can
cause problems with other background tasks. The more efficient (and
Raney-approved) method is to use built-in Rev messages to do the polling
