    abstract class for wrappers of geometric objects.

    These allows any geometric thingy to be used as a component in a view.

    (background info: geometrics are mathematical objects - they do not 

     keep any color or lineStyle attributes. Wrappers add this information

     and can also be used as components of a view)

    Notice: 

        this class was implemented using protocol information

        from alpha testers, from reading PD programs and 

        from the Hopkins/Horan book.

        - it may not be complete or compatible to the corresponding ST-80 class. 

        If you encounter any incompatibilities, please forward a note 

        describing the incompatibility verbal (i.e. no code) to the ST/X team.
