// CLASS:    MDrawInfo
//
//    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.
