#37 Collapsing a GroupGraphic to zero area
Reproduce:
1) Run Convey
2) New Canvas...
3) Draw a Freehand Graphic and one other Graphic
4) Select All
5) Group
6) Select mode
7) Scale the Group to zero area.
8) Try to click the single control handle and expand to a
nonzero area.
It looks like FrehandGraphic collapses to the origin.
