Ebrahim Byagowi 63109432cf Cosmetic and minor changes 2018-10-13 07:23:33 -04:00
Behdad Esfahbod c0a6814b49 Touch up new API 
New API:
+hb_ot_layout_feature_get_name_ids()
+hb_ot_layout_feature_get_characters()
 2018-10-12 16:06:39 -04:00
Behdad Esfahbod 477bc9aafe Add hb-ot-name.h 
Actual name-fetching API to come later.

New API:
hb_name_id_t
HB_NAME_ID_INVALID
 2018-10-12 16:06:39 -04:00
Ebrahim Byagowi dc49bd8d81 Add two APIs for getting stylistic set labels 
* hb_ot_layout_feature_get_characters
* hb_ot_layout_feature_get_name_ids

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

Behdad Esfahbod e9f9c0d81c [sanitize] Reorder condition to silence bogus gcc warning 
Was givin a dozen of:

../../src/hb-machinery.hh: In member function ‘bool AAT::ankr::sanitize(hb_sanitize_context_t*) const’:
../../src/hb-machinery.hh:307:23: warning: missed loop optimization, the loop counter may overflow [-Wunsafe-loop-optimizations]
     bool ok = --this->max_ops > 0 &&
               ~~~~~~~~~~~~~~~~~~~~~~
        this->start <= p &&
        ~~~~~~~~~~~~~~~~~~~
        p <= this->end &&
        ~~~~~~~~~~~~~~~^~
        (unsigned int) (this->end - p) >= len;
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I believe those are bogus, but this silences them and does not introduce
logic issues I believe.

Behdad Esfahbod 1a6b5ac6c3 Add HB_DEPRECATED_FOR and mark relevant symbols 2018-10-12 16:06:39 -04:00
Behdad Esfahbod c9413d7bb5 [graphite] Add HB_DEPRECATED annotation 2018-10-12 16:06:39 -04:00
Behdad Esfahbod 68c86af187 Always compile deprecated symbols 
We haven't been keeping this updated.  So, while we don't expose the
symbols in the headers if HB_DISABLE_DEPRECATED is defined, we still
always build them.

Behdad Esfahbod bf8469be9a Attach CursivePositioning backwards, not forward 
This is how Uniscribe does it.  So, adjust.  This is only relevant
to fonts that apply cursive positioning from a contextual lookup.
