One thing - transparent background is important. I notice there is a png
called rfz.png which has a white background. This worked as a pixbuf (I
think because I added an alpha channel based on that value), but it now
displays as solid black.

I think vectorizing pngs might not give very pretty results. It's a just
slipped back down the priority table as the cairo loading of pngs seems
to be working now. Getting the width and height information gets the
pngs in the right position - can you check that this is compiling ok on
gtk3 - I've checked it into git.
