If Fontography stores kerning tables in the bitmaps they've done some pretty
nifty programming. Bitmaps are graphics, not mathematical representations as
are Postscript fonts. A bitmap font is a simple picture, that's all.

The kerning information is in the Postscript printer font, and not in the
PPD (Postscript Printer Description) as you stated earlier. The PPD files,
whether on a Windows or a Mac, is a plain text file that contains the
printer's characteristics, such as printable area, resident fonts, halftone
screen frequencies, etc.
