  Ok, I am much happier with this fix now, it doesn't feel like a temporary hack anymore :).

  I have revised the fontLookup() algorithm in FontInfo so it now first tries to find matching font triplets by iterating over all the font family names *without substitutions*, if this fails it then iterates over all the font family names looking for matching font triplets *with substitutions* rather then just take the last one in the font family name list with substitutions.
