[xmlroff] Initial pangogp (GNOME Print) backend

[Tony G. <Ton...@Su...>]

I have checked in an initial pass at a GNOME Print backend for
PangoPDF.  See the CVS link at http://pangopdf.sourceforge.net/.

At this point, the pangogp-to-pdf program in the examples directory
produces a PDF file.

Caveat hacker.

Thanks - please keep working at this!  Being able to print FO documents using 
GnomePrint will be very useful for the free XML editor I'm working on 
(www.conglomerate.org).  Sorry I can't contribute directly.

Have just had a quick browse through the code.  I have two questions:

(i) Am I right in thinking that this lets you render a PangoLayout to a 
GnomePrintContext, and, in theory, wouldn't require PDFLib? (avoids 
dependencies, and licensing issues)

(ii) Am I right in thinking that the next stage is to have xmlroff implement 
GnomePrint as a FoDoc backend and that this isn't yet implemented?

Thanks (am stuck behind a _really_ slow internet connection so there's a 
limit to what I can download)

Correct.  There is no PDFlib dependency in the pangogp backend.

Correct, including the fact that this is not implemented yet.

There's more to it than just implementing a GNOME Print child type of
the existing FoDoc since, for example, PDFlib and GNOME Print have
different ways of handling graphics so presumably FoDoc has to provide
functions for handling graphics.

There's also the question that I put on the PangoPDF Wiki about
whether the GNOME Print glyphlist for a layout should be part of the
PangoContext (actually, PangoGPContext) or a parameter to
pango_gp_render(), etc.  Right now, pangogp avoids the issue by making
a separate glphlist for each run, which is not very efficient.

Also, there's a lot of '#include <pango/pangopdflib.h>' in the xmlroff
code that needs to be worked around.
