         How you implement this command is totally application dependent, but
         typical strategies include:

         - Perform an inverse operation on the last modified piece of data in
           the document. When redone, a copy of data stored in command is pasted
           back or some operation reapplied. This relies on the fact that you
           know the ordering of Undos; the user can never Undo at an arbitrary
           position in the command history.
         - Restore the entire document state (perhaps using document
-          transactioning). Potentially very inefficient, but possibly easier to

           code if the user interface and data are complex, and an "inverse
           execute" operation is hard to write. The docview sample uses the
           first method, to remove or restore segments in the drawing.
