     DESCRIPTION

          pdr is the draw routine for filled polygons.  You draw a

          typical polygon with a pmv, a sequence of pdr and close it

          with a pclos.  For example, the following sequence draws a

          square:


          pmv(0.0, 0.0, 0.0);

          pdr(1.0, 0.0, 0.0);

          pdr(1.0, 1.0, 0.0);

          pdr(0.0, 1.0, 0.0);

          pclos();
