Bug#742767: TeX Gyre OpenType and wrongly(?) named glyphs

[karl@freefriends.org (Karl Berry)]

    The problem is that the ligatures are named
            f_i

Adobe wants it that way these days, as I understand it.  (Personally I
think they were terribly wrong to try to change something so fundamental
but, surprisingly, they didn't ask me. :)

See section 6 (or search for ligature) in
  http://sourceforge.net/adobe/aglfn/wiki/AGL%20Specification
(and probably other adobe documents too, that's just what I found first).

In practice, since rendering software is so random about it, perhaps
fonts should include ligatures under both names.  Sigh.
