    #	  Use this function to register the widgets that will be re-configured
    #	  in their properties/class with the ::Apply() member function.

    # See Also  : themes::RegisterWidget
    # Synopsis  :
    #	  Reconfigures the stated properties of the registered widgets.
    #	  Only those widgets will be configured. If you want to
    #	  do a deep (recursive) reconfiguration down the tree/children,
    #     then you must use ::ApplyDeep() which requires specifying the
    #     parent widget among other things.
