Undo/Redo for objects can operate at two levels.

1) Gnumeric controled properties
    - existence
    - placement
    - size

2) Object controled properties
    - attributes
    - size ??

The former are well defined and should be supported by th
GnumericCommand apis.  The latter will require some form of Bonobo
api.  I have not researched whether or such a thing already exists.
