I'm rendering text to OpenGL via FreeTypeGL (which calls FreeType)

The font face is "Arial Unicode MS" (loaded from
"C:\Windows\Fonts\ARIALUNI.TTF") and is sized to 9pts at 96dpi.
When comparing the rendering of this text using the Windows GDI APIs
vs. the FreeType rendering I'm seeing a small difference. The GDI
rendering results in a slightly wider string.
I suspect that OpenGL only uses the kerning from the `kern' table,
while MS Windows uses the kerning from the `GPOS' table (Arial is an
OpenType font, AFAIK) which usually contains much more kern pairs and
probably even different values.
