Subject: Use cairosvg rather than librsvg to convert SVG to PNG.

librsvg now uses rust which I really don't want in my build chain.
cairosvg on the other hand uses python, which already is in my chain.

The downside is that we need to detect the binary name as often
it's based on the python version.
