Woo-Hoo!  :)
As one of those 'external libraries', I look forward to this!  (Although
I'm not really in a position to look into it at the moment... :( )

FYI - As word gets around that I'm starting to produce PDFs of our data
(Maps), a recurring question is if I can produce 'geopdf'.  From my
limited understanding/investigation, it's basically a PDF with a bunch
of specific tags in it.  Obviously all the geographic calculations and
issues are my domain, but until now, I couldn't see any way to get them
into the PDF file via the existing Cairo(mm) APIs. I wasn't thrilled at
the though of trying to edit the PDF file, or use an additional toolkit,
or something.  From the sounds of it, your basic metadata enhancements
should give me the piece that I need!  :)

Keep up the great work!
