The only significant change between vcg_1.30.orig.tar.gz (the old
obfuscated version) and vcg.20050204.tgz is in the copyright notice.
Almost all of the differences can be removed by running the following
on the old tree:

  for f in `find vcg.1.30 -type f`; do
    perl -i -e '$/ = undef;
                $_ = <>; s/Copyright \(C\) 1993(--1995|, 1994) by (Georg Sander, Iris Lemke|Iris Lemke, Georg Sander), and[\s*]+the Compare Consortium/Copyright (C) 1993-2005 Saarland University/gs;
                print;' $f || break

If #152128 is reproducible with the unobfuscated source but not with
the obfuscated one, upstream must have provided slightly different

Are you sure all that work is worth it?  Upstream hasn't made any
changes in eleven years; the prospective adopter hasn't moved an inch
in a year; and as far as I can tell from #288379, graphviz is a
reasonable alternative (and it's free software now).
