Dom has done great work getting the svg backend for gnome-print. Although
what he has now is more a proof of concept. Dom ran across some absolutely
fundamental limitations of gnome-print doing this. The SVG printing only
works for Latin-1 charsets at this point.

We also need to print the svg's. I guess this is some sort of svg ->
translation.

There is a lot of code on the internet that goes part-way to doing this
but I guess Dom and the gnome-print guys have their own plans...

Care to enlighten us Dom, Jody?

So is the idea we get an SVG and an XML representation of document via
this interface?

This is eaxctly the idea we (or at least me) have been thinking of.
