Hash :9eb6548d Message :[autofit] More tilde stretch support. (3/3)
The auto-hinter now supports up to four tilde glyphs (two above and two
below a base character).
Note that diacritics above (or below) a tilde are now also ignored by the
auto-hinter.
* src/autofit/afadjust.h (AF_ADJUST_TILDE_TOP2, AF_ADJUST_TILDE_BOTTOM2):
New macros.
* src/autofit/afadjust.c (af_reverse_character_map_new): Updated.
* src/autofit/aflatin.c (af_remove_top_points_from_edges,
af_remove_bottom_points_from_edges): Make functions also handle all
contours higher (or lower) of the given one in the argument.
(af_touch_top_contours, af_touch_bottom_contours): New functions.
(af_latin_stretch_top_tilde, af_latin_stretch_bottom_tilde): Use it to
also handle all contours higher (or lower) than the tilde contour.
* (af_latin_hints_apply): Handle more tilde glyphs.
