Chained Behaviors

[Peter Haworth]

Ah OK, that makes sense. I had the impression that each sprite needed
mouseUp logic that was unique to it.  I think I'm now seeing the usefulness
of this.

I'm thinking there might be a spot for a utility that, for any given
control, lists the message handlers it uses and where they reside.....
