  1. hiddenline.c -    Xlib-based program which uses the PolygonOffset
  2.         extension to do a hidden line rendering.  Depth
  3.         buffered black polygons are used to occlude the
  4.         hidden lines.  The PolygonOffset extension offsets
  5.         the polygons slightly so that their edges do not
  6.         interfere with the lines.  The program shows an
  7.         ordinary wireframe drawing, a hidden-line drawing
  8.         without PolygonOffset, and a hidden-line drawing
  9.         with PolygonOffset side-by-side so that it's easy
  10.         to compare the three techniques.
