Qunxin Liu 0d5695983e [subset] fixes dangling object_t issue in FeatureVariationRecord 
Fixes https://crbug.com/oss-fuzz/21560
revert () does not clean up useless object_t. Adjust the order of
subsetting substitutions and conditions to avoid dangling object_t.

Qunxin Liu c8cc1e378d fix issues in ClassDefFormat1 serialize: 
glyph ids in Iterator may be non-consecutive,

Qunxin Liu fcd7f33bbb [subset] GDEF glyphClassDef subsetting support 
glyphClassDef uses the same ClassDef format. However, glyphClassDef table
uses predefined class values so we do not remap class values.

Ebrahim Byagowi 5f23a76e99 [cff] Don't remove coords const qualification 
We should find some way to audit all the const removals, perhaps by
enabling -Wold-style-cast warning on the project and turning all the
implicit const removals to const_cast.

Fix collect lookups logic of FeatureVariationRecord 
As "Offset to a feature table substitution table, from beginning of the FeatureVariations table."
from https://docs.microsoft.com/en-us/typography/opentype/spec/chapter2 the record should
match its sanitize logic not the reverse way.

Fail serialize when map has incorrect value 
fixes https://crbug.com/oss-fuzz/19956

am not super happy with the fix, guess we should do some check
before the memcpy anyway as @blueshade7 thinks also,
so let's have it or revert it when we have a better approach for the case.

Jonathan Kew e5d6fe9782 Don't skip setting the .end field of the first range 
Fixes a bug in CoverageFormat2::serialize whereby the first range
was not serialized correctly if it consists of only a single glyph ID.
This broke shaping of U+0626 in the Arabic fallback shaper, because it
is not found in the coverage table of the 'init' and 'medi' lookups.

Also fix similar bug in ClassDefFormat2::serialize, noted during code
inspection (I haven't observed a case that was actually affected by
this, but it looks broken).

Ebrahim Byagowi 63109432cf Cosmetic and minor changes 2018-10-13 07:23:33 -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.
 2018-10-12 16:06:39 -04:00
Michiharu Ariza b51418f596 added CFF2 get_extents 
added source hb-ot-cff2-table.cc
