Werner: Thanks for getting back to me so quickly. I'm not delving into the 
TrueType file myself, I'm just using FreeType to open it and extract the 
goodies. How do I parse the 'kern' table? I have looked through freetype.h and 
I do not see any functions that provide access to this table.

For my purposes I don't need to get fancy with multi-dimensional kerning 
although once I get the basics down I will certainly be more than happy to see 
how much farther I can take it.

I'm trying to get FreeType font hinting to work in Juce.
