I seem to remember we discussed this a while back, but can't find it
now nor remember the conclusion.

There's also the issue of scaling the svg images using librsvg, which
can only scale using cairo or with a deprecated method.  If I read the
above thread correctly, the suggestions are:

1. Find a way to use librsvg + cairo to scale images in a toolkit
independent way.
2. Lars suggested to modify the XML (the svg file).
3. Change to a different svg library.

I'm not sure which of these would be the most practical.

Here's a relevant Stack Overflow question:
