Note that you should use FreeType 2.2.1 because in some older versions
FT_HAS_KERNING works incorrectly.

Probably. Kerning realized with a `GPOS' table isn't supported by
FreeType.

It really depends. The `easiest' route (w.r.t. code size) is probably
to extract the GPOS and GDEF tables directly and parse it by yourself
-- you might have a look at the otvalid module which assists in
verification of this table.
Note that the above approach gets quite complicated if your font
supports more sophisticated layouts or has unusual typographic
features.

Qt and ICU can do this too.
