Irregular shaped buttons redux

[Judy Perry]

Thanks, Scott.  I think it should work.  I had thought about using the
transparent portions of a rectangular image that way with the intersect
function but transparencies don't work that way apparently with that
function but they do with another and with respect to mouse events.  :(

I'll have a look at it.

Thanks again!
