  42.      All of the above routines are functionally the same.  They differ only in
  43.      the type declarations of their parameters and in whether they assume a
  44.      two- or three-dimensional space.

  47.      _n        expects the number of vertices in the polygon.  There can be no
  48.               more than 256 vertices in a single polygon.
  49.  
  50.      _p_a_r_r_a_y   expects an array containing the vertices of a polygon.
  51.  
  52.      _i_a_r_r_a_y   expects the array containing the color map indices which
  53.               determine the intensities of the vertices of the polygon
  54.

  56.      ssssppppllllffff draws Gouraud-shaded polygons using the current pattern and
  57.      writemask.  Polygons are represented as arrays of points.  The first and
  58.      last points automatically connect to close a polygon.

  74.      If you want to use bbbbaaaacccckkkkffffaaaacccceeee, you should specify the vertices in counter-
  75.      clockwise order.
  76.  
  77.      After the polygon is drawn, the current graphics position is set to the
  78.      first point in the array.
  79.
