A patch which brings SIPP, the Simple Polygon Processor, to version
2.0.2 has been posted to comp.sources.misc.  The patch fixes a bug
which sometimes caused SIPP to mark a polygon as facing away from the
viewer although in reality it did not.  Thanks to David G. Jones who
pointed out the bug to us and also gave us a test program.
