What an odd function...I had never had occasion to use PtToAngle.
It's actually very convenient. I used it in the original moose, to
make the eyes follow the mouse correctly. Of course, since I only
have about 9 different eye positions, it was easy to just hard code
the coordinates when I moved to quartz.
I could imagine it would also be handy, for implementing dials of
some sort. Pity there isn't a quartz equivalent. But then, the maths
isn't that difficult, and in other cases we have to do similar maths
ourselves, too.
