石垣さん、Turnerに議論したことを話したら、彼も同じことを考えたが、
font definition file と一緒に配布するのは、ファイルが大きすぎるので、
全ての言語対応は考えていないとのことでした。

Yes, I did wonder about that approach, but unfortunately I'm not sure that
it helps. In order to use gdImageStringTTF, I would have to distribute the
freetype library with analog, together with all the font definition files
for all the languages that I used. I don't see that there can be any way
round distributing all the font definition files, which would be a very
large download.
