After discussion we decided to include the configurations provided in a

Going forward we should work with fontconfig upstream on a solution
which allows use to import the system configuration instead.
We need at least the URW fonts configuration for correct PDF rendering as reported against firefox on https://github.com/ubuntu/gnome-sdk/issues/49
