    1. It implements the XPane interface.  This is the most important
    interface of this class for API based views (of which there not that
    many yet) because it gives access to the XWindow.
    2. It gives access to the underlying VCL Window by implementing the
    XUnoTunnel interface.  This is necessary at the moment and in the
