2d001a0adc [subset] OTS doesn't allow ligature attachment offset to be 0 2023-11-08 14:10:06 -07:00

9701b0024e [subset] Always place CFF1/2 char strings at the end of the packed table. 
Makes the behaviour from HB_SUBSET_FLAGS_IFTB_REQUIREMENTS the default.

c6884377ec [subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. 
When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2.

This change is a version of 3ae2fe2084 rebased onto head w/ tests added.

bbd53fcfa4 Remove glyph_map test that uses retain gids. 
We no longer allow the use of glyph map + retain gids (see: https://github.com/harfbuzz/harfbuzz/blob/main/src/hb-subset-plan.cc#L817). Also add the test to the meson file so it will be run by default.

2175f5d050 [subset] Fix inefficient ItemVariationStore subsetting w/ retain_gids. 
ItemVariationStore is relying on the assumption that the inner_map is populated for all output glyphs, this is not true for subsetting operations with retain gids enabled. Fixes fuzzer timeout: https://oss-fuzz.com/testcase-detail/4575222591520768.

af1e605be2 [instancer] bug fix 
It's possible that length of all_points equals to 4 for non-empty
glyphs: a composite glyph which contains only one child glyph that is
empty.
