       SippObjectDeepDup [-flags] objecthandle
              Copy the entire tree of an object, including subob-
              jects and all surfaces, polygons and vertices. This
              is a costly operation if the object is complex.

              The following optional flags may be specified:

                 o -cleartransf - Set the object's transformation
                 matrix to the identity matrix.  Default.

                 o -keeptransf - Don't reset the object's  trans-
                 formation matrix

              Clearing  the  transformation matrix has the affect
              of undoing all rotate, move and scale operations on
              the  object.   This  repositions  the object to the
              world center, which often makes moving  the  object
              to another location easier.  The transformations on
              subobjects are not cleared, leaving  the  structure
              of composite objects intact.
