72cbfb9059 remove empty lookup subtables 
Added a variant of subset_offset_array which takes an extra arg passed to serialize_subset for this impl.
Added a new api test "test-subset-gpos" for this.

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.

So we can use the version we like when we decide what it should be while the next release
and can review the API before the release one other time.

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.

Issue 1558: [subset] TrueType/CFF2 variable font
 2019-12-31 13:52:50 +03:30

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.

b618e0ae13 Remove non-breaking spaces from comments. 
`0xC2A0` was used, for some reasons. It's not really a problem, but Qt Creator
constatly trying to replace them with regular spaces, so I have to edit those
files separately.
