+//
+//    This class is used by the getDrawRequests method of MPxSurfaceShapeUI
+//    to specify the current object drawing state for a user defined shape.
+//
+//    The getPrototype method is used to construct a draw request object
+//    based on the current draw state for the object.
+//
+//    See MDrawRequest for more information.
