seems two different functions are used for tfm/vf width calculation. In
pdftex.web there is a macro store_scaled() for the tfm width, but for vf
scaling some C function sqxfw() (borrowed from dvipdfm) is used, and
they seem to behave slightly differently. Maybe if one would write a
Pascal function wrapper around store_scaled (which is the exact,
"official" TeX operation), one could get rid of sqxfw(). Just a wild
