Known bugs in epix-0.8.4 -- June 29, 2002

(contrib/epix_ext.cc)
The hatch_polygon routine from the contrib package is partially
broken, or partially fixed (as the case may be). Vertex arguments must
be passed explicitly as references. This will be fixed once the author
finds a good C++ reference that actually explains how reference
parameters work, rather than being "C++ for dummies". :|
