FT_Get_Kerning only has access to the old "kern" TrueType table, which
Calibri does not include. Kerning in Calibri is realized only using the
modern "kern" feature implemented in the "GPOS" OpenType table. To
access that table, you should use an OpenType Layout engine such as
HarfBuzz, Pango, ICU Layout, Uniscribe, Bitstream Panorama or Monotype
WorldType, before you use FreeType to perform the glyph imaging.

This is a good idea anyway. FreeType is useful to perform glyph imaging,
but its text layout abilities are very limited.

Best,
Adam
