    	---Purpose: WFDeflectionRestrictedFace    -    computes    the
    	--          wireframe   presentation   of  faces       with  
    	--          restrictions by  displaying  a given  number of  U
    	--          and/or  V  isoparametric  curves,  converts his
    	--          into VRML objects   and writes (adds) them  into
    	--          anOStream.    All   requested properties  of the
    	--          representation  are  specify in  aDrawer of Drawer
    	--          class (Prs3d).    This kind  of the presentation
    	--          is     converted       into   IndexedFaceSet   and
    	--          IndexedLineSet ( VRML ).
 
        --          The  isoparametric  curves  are drawn  with  respect to a
        --          maximal chordial  deviation. The presentation includes
        --          the restriction curves.
