2018-09-04 11:29:15 -07:00
Michiharu Ariza f2d299b0b7 Drop hints from CFF2 charstrings

Michiharu Ariza 633ce88de9 CFF Subrs subsetting
Unreferenced subroutines are nullified (not removed) in a subset font

Separate Interpreter struct from hb-ot-cff-common-private.hh in a set of four header files, augmented for CharString (CS):
hb-cff-interp-common-private.hh
hb-cff-interp-dict-common-private.hh
hb-cff-interp-cs-common-private.hh
hb-cff-interp-cs.hh

Interpreter runtime is separated off as a new struct InterpEnv sub-classed differently for Dict and CharString (CS)
2018-08-15 12:00:19 -07:00
Michiharu Ariza 64c5412264 Added CFF support
Added sources hb-ot-cff-table.hh, hb-subset-cff.cc & hh
Templatized Index because CFF uses 16-bit count while CFF2 uses 32-bit
Misc code cleanup & bug fixes
2018-08-10 11:07:07 -07:00
Michiharu Ariza 5561b81849 subset FDSelect and FDArray
Added a set of sources hb-subset-cff-common-private.cc & .hh for FDSelect subseting code.
Added FDSelect format 4 (CFF2 only) support. Shared its implementation with format 3 as a template.

Michiharu Ariza 00970dd242 Removed parsed hint fields from CFF2PrivateDictValues
Instead moved & stored uniformly in values vector (renamed from opstrs)
This should be fine as we aren't likely going to use them as hints after all
Templatized DictValues whether to parse them out
For subsetter, they aren't parsed
