* Sync with Debian; Ubuntu changes are:
  - Add patch 30_anymetrics, turns on FC_ANY_METRICS whenever looking up
    fonts with fontconfig; lets fontconfig's configuration know that we
    don't care about getting a font with exactly the same shape as the
    family we asked for and fixes (eg) a firefox vs. evince font metrics
    ugliness issue.
