Ebrahim Byagowi da37880e17 [draw] Add a private bit field instead null-checking quad-to callback 
This doesn't imply the the design is good or stable just is better
to not fail due to null quad-to callback so as our quad-cubic curves
translation is currently table limited which can be revisited anytime.

Ebrahim Byagowi ff984ed3cd Use multiplication to avoid undefined behaviour per clang 
Newer versions of MSVC with /we4146 don't like putting negative sign behind a
unsigned number as https://github.com/harfbuzz/harfbuzz/pull/2069
That however have made https://crbug.com/1050424 this complain:
  src/hb-ot-color-sbix-table.hh:304:28: runtime error: negation of -2147483648 cannot be represented in type 'int';
                                        cast to an unsigned type to negate this value to itself
which apparently can be fixed using this change.

Let's see if this won't make another ubsan complain!

Ebrahim Byagowi 40166eb0e5 [var] Fix the just introduced hb_font_set_var_coords_design storing bug 
The memcpy call was using the current coords count which is zero initially so no copy at all.

Sad that no test has caught it, should see why, will however with the upcoming style API tests.

Garret Rieger 5a10f3a055 Use vector instead of map during page compaction in hb-set. 2020-02-08 10:27:44 +03:30
Garret Rieger 2742c81624 Fix page_map corruption in hb_set_t during process(). 
If a process operation results in less pages then the current set has, it will likely corrupt the page_map since it overwrites page_map entries ahead of where it's processing. This fixes that problem by removing page_map entries that will be dropped. Then dropping orphaned pages and re-indexing retained pages.

 2019-12-31 13:52:50 +03:30
Khaled Hosny 68c1798a67 [coretext] Use kCTFontOpenTypeFeatureTag 
Instead of trying to map OpenType features to AAT feature selectors
which only works for a small subset of OpenType features, use the
simpler kCTFontOpenTypeFeatureTag with OpenType feature tags directly.

With this change, features like cvXX can be enabled in coretext shaper,
while they were previously ignored due to missing mapping.

This seems to work even with AAT fonts that don’t have OpenType layout
tables, which suggests that CoreText is doing the mapping itself in this
case.

kCTFontOpenTypeFeatureTag seems to have been introduced in macOS 10.10
and iOS 8.0, though, so its use is conditional on version check for now.
Not sure how to check iOS version, so I left this out.

Ben Wagner b918cd8c76 Document hb_feature_t. 
This documents hb_feature_t. This is motivated mostly by the ambiguity
of the units for 'start' and 'end' (clusters) and whether they are
inclusive or exclusive. This also documents that for lookup type 3 the
value is the one based index into the alternates and that in a list of
features later feature values override previous feature values with the
same tag.
