[XeTeX] font expansion (again)

[Pablo Rodríguez]

Hi Jonathan,

I have a question about the experimental version: do you plan to include 
font expansion?

I don't know how much this implementation differs from the margin 
kerning, but I guess this would be easier to deploy by users than margin 
kerning, since the same value would be applied to stretch or shrink all 
glyphs in a font.

I guess this might be of interest to other members of the list.

Thanks for the further XeTeX development,


Pablo
