vertical: improve glyph positioning
It is a bit crazy, but for vertical layout the sTypoAscender and
sTypoDescender fields of the OS/2 table are supposed to be used for
determining the size of the ideographic EM box [1], so that glyphs
can be centered on the baseline more neatly.
With this change, vertical layout should be completely equal to
VSFilter.
