In an earlier post (which I have lost) someone mentioned that GPOS
kerning might me usable to deal with the distortions implicit in grid
fitting. 

The LookupType 2 sub-tables (pair adjustment -- ie kerning) of GPOS
allow for a "device table" which can contain a correction for each
letter pair in pixels for any given ppem. 

They don't seem to have a connection to tt points (nothing the grid
fitting instructions could control)... probably a good thing given the
combinatorial number of points that would be needed for kerning.
