  1. [fontir] Round sub/sup Y offsets before deriving X offsets 

    ufo2ft's OS/2 builder stores each sub/superscript value as
otRound(value) and then derives the X offsets from the *stored*
(already rounded) Y offsets.

fontc fed the raw fallback float (upem * 0.075, upem * 0.35) into
adjust_offset instead. For a upem where those products are not
integral, and a non-zero italic angle, the derived X offset can round
to a different integer than fontmake's.

This... doesn't really matter, but the new code isn't any worse than the
previous code, and it makes some numbers green.
