Hi Fred,
I looked at librsvg a bit (here is the latest release: 
http://git.gnome.org/browse/librsvg/tree/?id=2.34.0 - the website at 
http://librsvg.sourceforge.net/ is out of date). It should be pretty 
straightforward to wrap in an NSImageRep, hopefully no more than a few hundred 
lines. btw, if you pass it a cairo surface, it will draw directly on that 
instead of rasterizing to a bitmap first. Not sure if it would be worth trying 
to take advantage of that, but we could.

Also, I started to write an NSImageRep subclass which calls Ghostscript via 
NSTask to render ps/eps/pdf's. It's not a very elegant solution but there are 
no other viable options I can see.
