Update: 3-Apr-2000				John Hobbs

1) Major modifications to GeometryElement interface.   The changes
   remove support for the "position relative to default geometry"
   maintained within GeometryElement itself.

   Changes to public interface (GX is shorthand for GeometryXform):

      get_offset()         - Deleted
      set_reference_xform  - Changed to two methods:
                                set_position(GX& absolute)
                                set_relative_position(GX& parent, GX& offset)
      get_reference_xform  - Changed to method
                                get_relative_position(GX& parent);


   Internal changes (private):

      _relative_position   - Removed

2) Add geometry observer interface for local caches of geometry.
3) Fixes for Kai3.4 (unprototyped operators in dgs namespace.
