Gesture Listener

[Jim Colton]

What I think happens is what I stated in my original mail.  ;)   Each
application that has registered a doLayout() callback with the gesture
listener gets laid out again and therefore each component of the layout will
know it's new position and dimension so that touch screen events for it can
be identified and acted upon.  A button component for example.
