Okay -- but what are the differences between ESP Ghostscript and the
Ghostscript package we actually ship?  Ours is based on GNU
Ghostscript, but has lots of other patches integrated.  What
functionality would need to be ported to ESP Ghostscript to maintain
the same level?

But these are relative to what?  GNU Ghostscript?  What I'm personally
interested in is a comparision between ESP Ghostscript and the
Ghostscript package we are currently shipping.

With respect to switching to ESP Ghostscript for the next development
cycle, one drawback that seems immediately apparent is that ESP
Ghostscript is not based on GNU Ghostscript 8.x!  If we stick to GNU
Ghostscript we'll be able to upgrade to 8.x.
