There is no special cache for kerning values.  For simple fonts
(horizontal kerning with PostScript Type 1 fonts or TTFs where the
information is in the `kern' table) it is sufficient to call
FT_Get_Kerning.  For sophisticated kerning handling (this is, the
kerning data is context specific and thus stored in a `GPOS' table, or
you need vertical kerning) you should use a higher-level library like
`Pango' or `ICU'.
