class WFRestrictedFace from VrmlConverter 


    	---Purpose: WFRestrictedFace -     computes     the  wireframe
    	--          presentation  of faces  with   restrictions by  
    	--          displaying   a  given  number    of  U   and/or  V
    	--          isoparametric  curves,  converts this  one into VRML
    	--          objects  and writes  (adds)  into anOStream.
    	--          All requested  properties  of the representation
    	--          are specify in  aDrawer.
    	--          This kind of the presentation is converted into
    	--          IndexedLineSet ( VRML ).

        --          The isoparametric curves are drawn with a fixed
        --          number of points.
