Rectify latest cairo SVG export
It seems Cairo got updated and its SVG export is now broken in a new and exciting way. Now it exports documents with dimensionless w/h. The issue with that is that Cairo thinks that means point @ 72 pt / inch, but everyone else including the actual svg spec interpret that as raw document units or pixels, AFAICT completely breaking dpi scaling in common viewers. Since we have to mess with Cairo's SVG files anyway, we just fix this as well by re-writing the broken w/h into physical units according to a hardcoded conversion factor that matches cairo's hardcoded scale.
