I've pushed a changeset.

        http://hg.savannah.gnu.org/hgweb/octave/rev/d5a7db05d591

There are two "features" I'm aware of.

(1) Cropping the EPS files produces by GL2PS removes the axis and tick labels. 
This can be seen by adding the -tight option to the print command.
(2) Appending PS files from GL2PS mangles the fonts.

I don't have a solution for (1). For (2) a PS wrapper can be used.

        
http://en.wikibooks.org/wiki/PostScript_FAQ#How_to_concatenate_several_PS_files.3F

That solution looks messy to me. Is there a better way?

In addition to adding the PS and PDF output, I've included several bitmap 
devices that are supported by Matlab. This was a trivial change since 
ghostscript does all the work.

As I mentioned above, support of GL2PS_TEX, GL2PS_SVG, GL2PS_PGF still needs to 
be included by someone more skilled, than myself,  in c/c++. Until that happens 
the effected devices (epslatex, epslatexstandalone, pslatex, svg, tikz), will 
produce eps output.
