Creating pdf documentation images with Octave

[Rik]

Ben,

Sometime ago we switched away from using Octave to generate the pdf images
for the documentation to using ghostscript to render the eps into pdf
format.  This was due to problems in the printing backend at the time.
Have those issues been resolved and can we switch back?

I just sample checked a few of the images generated by plotimages.m in
doc/interpreter and they seem to be created correctly.  Currently the eps
and png formats are created from Octave and the pdf by the Makefile via
ghostscript, but it would be nice to have the documentation printing be
unified with everything produced by Octave.
