Thanks. That clarified a lot for me.

I think you meant Pango here. Pango replaces Fribidi and FontConfig so
it had better go in a separate module. HarfBuzz, as far as I know,
replaces neither so it can go in the same freetype module, which is
what jb suggested. And of course it can be isolated in its own source
