You want documentation?  Don't you know this is an open-source project?

I'll see what I can do.

Cairo (http://www.cairographics.org) is the next Big Thing for free software
to use for rendering.

It's also required for recent Pango builds, so sooner or later it will be on
every machine that has GNOME anyway.

configure checks both for Cairo and for a recent enough version of Pango,
since you need both.  If you disable Cairo, the required Pango version reverts
to 1.6 or so.

Cairo looks like the best way to get SVG support in xmlroff, since lots of
people seem to be hooking libsvg up to Cairo.  I haven't looked into the
details, but it would be an ideal task for someone who is interested in SVG
support.

The Cairo backend doesn't (yet) replace anything.  It's currently an
alternative to the GNOME Print default.
