Should the assignment to z be shifted down 6 lines, so that, 
like the other changes, it comes below the "else" ? 
 
            clip_move(x, y); 
            z =  (points[i - step].z + points[i].z) * .5;  <=== is 
#ifdef PM3D 
            if (color_from_column) 
              z =  (points[i - step].ylow + points[i].ylow) * .5; 
            else 
#endif 
                                                           <=== ?? 
              set_color(z2gray(z)); 
            clip_vector(xx0, yy0); 
      } 
    }
