Behdad Esfahbod 188ee6e5ee Calculate anchor positions in float, then round
Hoping to reduce rounding error, to make tests happier...
No luck.

Behdad Esfahbod 7cdd6ab068 Round, instead of floor, when applying variations
Hoping this would fix remaining text-rendering-tests failures,
but so far no luck.

Turns out I don't need this to resolve CoreText optical sizing
issue after all.

Behdad Esfahbod 26648cebcd [GX] Remove (partial) support for anisotropic variations
It doesn't always work, not part of FreeType, and we were not going
to expose it in the API anyway.  Can always be added later.

2016-06-06 23:08:54 -07:00
Behdad Esfahbod 8b5bc141cd Add get_nominal_glyph() and get_variation_glyph() instead of get_glyph()
New API:
- hb_font_get_nominal_glyph_func_t
- hb_font_get_variation_glyph_func_t
- hb_font_funcs_set_nominal_glyph_func()
- hb_font_funcs_set_variation_glyph_func()
- hb_font_get_nominal_glyph()
- hb_font_get_variation_glyph()

Deprecated API:
- hb_font_get_glyph_func_t
- hb_font_funcs_set_glyph_func()

Clients that implement their own font-funcs are encouraged to replace
their get_glyph() implementation with a get_nominal_glyph() and
get_variation_glyph() pair.  The variation version can assume that
variation_selector argument is not zero.

Steven R. Loomis a13b023dbf AIX fixes
- use '-w' instead of '\<...\>' for check-header-guards
  grep manpage says these are the same

- put '-q' first in the grep options

- move VAR into hb-private.hh

- hb-font-private.hh - use [VAR] instead of [] for variable array

Behdad Esfahbod 762770c964 Add font->has_...() to check for individual nil font funcs
Hopefully this wouldn't break any compiler.  There was some magic
moments to getting this to compile...

Behdad Esfahbod 5a5350b39b Revert "Round when scaling values"
This reverts commit 10f964623f.

See discussion with Khaled Hosny on mailing list.  In short, since
integers here can be negative, and int division is "round towards
zero", proper rounding should take sign into account.  Just skip
doing it again, has been serving us well before.

Behdad Esfahbod 10f964623f Round when scaling values
Doesn't matter for most users since they should be working in a
fixed sub-pixel scale anyway (ie. 22.10, 26.6, 16.16, etc).
