    abstract superclass for all kinds of wrapping components

    This class and its subclasses (currently) exist mostly for

    ST-80 compatibility - to provide a home for ported PD classes,

    which depend on the VisualPart hierarchy.

    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.

        This is still being constructed - not yet finished.

    [author:]

        Claus Gittinger
