              CreateManipulator generates  a  DragManip  with  a  RubberRect  to  provide  visual  feedback  for
              specifying  the rectangular area to be magnified.  InterpretManipulator does not create a command;
              rather, it examines the DragManipulator's RubberRect and calls Magnify  on  the  viewer  with  the
              RubberRect's final coordinates.
