Firefox 3 apparently implements a little-known CSS 2.0 property for
specifying the font size by x-height:

This doesn't provide for making the leading differ between faces, but if
the x-height is fixed, and the leading is set in the same units, then
that might suffice.  (But I haven't tried playing with it.)
