I wrote ftx backend before writing xft backend because the documentation of Xft library was poor (even now so) and it was easier to debug the font-backend mechanism with ftx backend (because it directly uses freetype). I don't know how many systems have X but not Xft, but if there exists such a system, ftx backend is still necessary. --- Kenichi Handa handa@m17n.org
