                 plwf, z
              or plwf, z, y,x

         plots a 3-D wire frame of the given Z array, which must have the
         same dimensions as the mesh (X, Y).  If X and Y are not given, they
         default to the first and second indices of Z, respectively.
         The drawing order of the zones is determined by a simple "painter's
         algorithm", which works fairly well if the mesh is reasonably near
         rectilinear, but can fail even then if the viewpoint is chosen to
         produce extreme fisheye perspective effects.  Look at the resulting
         plot carefully to be sure the algorithm has correctly rendered the
         model in each case.
       KEYWORDS: fill   -- optional colors to use (default is to make zones
                           have background color), same dimension options as
                           for z argument to plf function
    	     shade  -- set non-zero to compute shading from current
    	               3D lighting sources
                 edges  -- default is 1 (draw edges), but if you provide fill
                           colors, you may set to 0 to supress the edges
                 ecolor, ewidth  -- color and width of edges
    	     cull   -- default is 1 (cull back surfaces), but if you want
    	               to see the "underside" of the model, set to 0
    	     scale  -- by default, Z is scaled to "reasonable" maximum
    	               and minimum values related to the scale of (X,Y).
    		       This keyword alters the default scaling factor, in
    		       the sense that scale=2.0 will produce twice the
    		       Z-relief of the default scale=1.0.
    	     cmax   -- the ambient= keyword in light3 can be used to
    	               control how dark the darkest surface is; use this
    		       to control how light the lightest surface is
    		       the lightwf routine can change this parameter
    		       interactively
