I'm not very well acquainted with the cache code, but I seem to
remember that glyph metrics and kerning data are *not* cached. You
have to do that by yourself -- I think it should be possible to use
the generic FreeType cache functions to model something after, say,
`FTC_CMapCache'. Look at the code in src/cache/ftccmap.c. We would
be happy if you could then contribute your code to us.
