    this class will (eventually) allow parsing windowSpecs as
    created by ST-80's UIPainter, and thereby allow to run applications
    built with this tool.
    It was created to allow execution of PD applications which were
    written using that tool (and more and more are appearing ...).

    The class is not completed yet and certainly not bug free.
    Also, it is not quaranteed that all winSpecs are understood.

    Notice: 
        this class was implemented using protocol information
        from alpha testers, literature and by read public domain code
        - 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.
