[autofit] Fix vertical adjustment of (mainly) double diacritics.
The series of commits that introduced this adjustment support had some
flaws.
- If there were two diacritics on top of a base glyph, and the upper
diacritic was a tilde, the vertical centering correction was incorrectly
applied to the lower, non-tilde glyph instead of the tilde.
- The maximum value allowed to shift a glyph was too strict (and also not
handling rounding issues), causing some diacritics and combinations of
diacritics to be not shifted at all.
* src/autofit/aflatin.c
(af_glyph_hints_apply_vertical_separation_adjustments): Correctly handle
vertical centering correction.
