The main problem with "virtual" and "edge" (and it's to some extent, shared 
with "body") is in finding the outer edge of the object or shape. And this
is fairly common to all types of elements.

True.  But then every bit of code which dereferences a CP will have to take
this difference into account -- yuck -- 

Saw your page on faemalia; makes a lot of sense.
