Then this would imply that Imagine creates a discontinuity in the object's
surface which would be EXTREMELY undesireable. In other words, gaps will
form between the bone assigned surfaces and the non-bone assigned surfaces.
The only way to prevent such gaps would be to allow one of the two adjacent
surfaces to stretch.

Side view     __.__.__    __./        __.
                         stretch     no stretch

In the mini diagram, the first surface is not assigned a bone while the
second two surfaces are. So are you sure that Imagine simply repositions
the polys without any stretching from unaffected surfaces?
