  18 C-  Calculates the coordinates of the corner points of a GEANT  shape
  19 C-  from the shape parameters.   The end faces are generated by drawing
  20 C-  connected polylines between the corner points at each Z-end of the shape.
  21 C-  A ruled solid is then defined between the 2 faces, and written out in SET.
