    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.
