Re: Improvements to Postscript backend (new patch)

[David Feuer]

I haven't yet found a better name for str4, or written a comment about
kerning, but I've made enough improvements that I think it's time to
send the patch in again.  Diff apparently got sick of all the changes
in output-ps.scm, so it did a really lousy job, even with -d.  Sorry
about that.  Reminder: this patch is against 2.8.0.  I strongly
suggest that you _not_ attempt to apply it to any version of
output-ps.scm other than that, because it will fry.  I'd like to
discuss conventions for PostScript at some point, but right now I have
to go.  Basic question: should drawing procedures all start at the
current point (they don't now)?  Should they all start at (0,0) (they
don't now)?  Or should some start one place and some another place,
with some kind of system for deciding?  I don't know if I'll be able
to do any more work on this for a while, so I'd appreciate if someone
else would take care of any small changes that may be necessary (e.g.,
to variable names).

Changelog:

Changes to PostScript backend:
glyph-string now produces smaller, more readable, and probably faster PostScript
Several findfont scalefont setfont instances changed to selectfont
Hacked-up string-appends changed to formats.
