Bug 80129

I've done a first-cut port of the new espgs that uses ghostscript 8.15, as
available from the CUPS folks.  I've been using it for quite a while now; it
solves some problems I was having with failing Postscript print jobs and has
given me no trouble at all.  It may not _quite_ be in the best shape for a
port, but I thought I would pass it on so others can get the benefit of it.
Unfortunately, I have no time to clean it up.

I sent email to ports at one point, but got no response.  Here's the email:

The CUPS folks have made their new integration of espgs with ghostscript
8.15 available as an initial release candidate.  Having run into a problem
this weekend that a newer ghostscript would solve (having to do with getting
an -invalidfont- error), I found it and hacked up a quick-and-dirty port.

I'm not opening a PR because this thing is definitely _not_ ready for prime
time and I have no time at the moment to make it so, having started a new
job last week.  I'm therefore making the patch (and distfile, just in case)
available on my website; the patch is 'cups-pstoraster-espgs815.patch' at
http://www.exit.com/Archives/ and the distfile is in the Distfiles directory
below that.

Most notably, this thing installs espgs as a regular ghostscript port, but
the pkg-plist is still the cups-pstoraster port.  I just thought that this
might make a reasonable starting place for whoever wants to pick it up from
here.
