[squeak-dev] How to Drag the Scenery

I would like to implement a kind of portal class where the portal is a
viewer into a PasteUpMorph which is possibly much larger than the portal.
The PasteUpMorph is a submorph of the portal (and the portal itself is
likely a subclass of PasteUpMorph). The portal will have "active borders" a
few pixels wide. The behavior I want to implement will work like this:
If a drag is started from inside the border, it drags the underlying
PasteUpMorph with it.
I need some suggestions of code to read as an example of how to do this.
-Thanks in advance, Jim
