I don't think there is any :-)

* Load svg file into a surface cache w/ transparent background:

Have a look at _make_buffer() in 
http://196.211.3.106/cgi-bin/trac.cgi/browser/Survival/ontology/thing.py

[ a self.svg can be constructed w/ self.svg = rsvg.Handle('filename') ]


* Measuring svg files size / knowing what size to render it:

Gnnnngggg. Ask me again when I'm not halfway through changing how I 
handle transforms in my code and feel like I'm a privileged observer of 
an absolute space time continuum!!

You should be able to get a better idea from the code ref above than 
anything I could come up with in my current mood.

Hope this helps!
