What happens (from HandMorph>>grabMorph:) is:

* Morph is removed from world -- invalidate rectangle of World
* Morph is added to Hand -- invalidate rectangle of new hand bounds, 
including drop shadow.

but this happens in the same update cycle and so the rectangles should 
get merged into a single damage rectangle.

However... the two rectangles don't seem to be merging.
