Just so I can close an "ancient" PR, I made a xditview package as per
pkg/2393.  However, I really have no idea how to test it because I
don't know how to use it.  It's at

	http://www.stat.cmu.edu/~lamj/xditview.tgz

and extracts into /usr/pkgsrc/print.  Can anyone else look at it and
perhaps tell me if it's okay to commit?

	Thanks,
