If you look at Apple's AAT stuff
        http://developer.apple.com/fonts/TTRefMan/RM06/Chap6fvar.html
        http://developer.apple.com/fonts/TTRefMan/RM06/Chap6gvar.html
They provide a mechanism for optical sizing as well as other varients found 
in multiple master fonts.

Essentially the gvar table (glyph variation) contains delta instructions to 
move points in glyphs for each supported stylistic variation.
