Bob --

It's likely that that FreeType is fine.
     (Andrew is more cautious ...)
I was at Apple when the TrueType stuff was done and I don't recall them
doing anything that wasn't in prior art in the 70s (the outline font idea
was first done by Patrick Baudelaire at PARC, Dick Shoup and I (and
Negroponte's group at MIT) did various early version of antialiased fonts
and came up with algorithms for same, Warnock at E&S and then PARC
experimented with outline font conversion, hinting, etc., Knuth did many
wonderful things in his pursuit of computer generated fonts, etc.). All of
these are on record. It's the patent office that is to blame for much of
this, in that they have been willing to grant patents on just about
anything for the last 30 or so years without vetting them, but simply
leaving it up to unsophisticated people in civil courts (or out of court)
to resolve issues. This has been/is terrible and needs to be combatted.

Cheers,

Alan
