IIRC Davide Viti of the Debian font team has a font regression suite. It
would be nice to package it and use it for all our font packages

http://d-i.alioth.debian.org/gtk-frontend/screenshots/

BTW your testing with OO.o is non-representative as it uses its own font
stack different from the one every other app uses. IIRC right now you
have GTK-style font rendering (pango...), QT-style font rendering (being
merged with the GTK one at f.d.o), and one-of-a-kind OO.o & java font
rendering.

Since you're going to be responsible for a highly visible font package
it might be a good idea to drop in one of freedesktop's text layout
summits http://www.freedesktop.org/wiki/TextLayout to make contacts and
make some publicity around Liberation.
