David Corbett 916c5a9007 Consistently emit BCP 47 subtag scope suffixes 2020-10-11 11:38:40 -07:00
Behdad Esfahbod 1c05f6789b [buffer] Increase work limits 
Our previous limits of 64 per input character was already hit
by David Corbett's under-development Duployan font.

Increase work limits by factor of 16, and number of glyphs by factor of 2.

Fixes https://github.com/harfbuzz/harfbuzz/issues/2707

Behdad Esfahbod b37edebfcb [buffer/deserialize] Do not clear() buffer upon content type mismatch 
We return false. I don't see reason to clear buffer.

Simon Cozens 7c0bc0bb92 Serialize invalid buffer to !! (text) or [] (json) 
There is no generic deserialize - you have to choose glyphs or unicode - so there is no way to deserialize this buffer.

Note that now JSON glyph buffers and Unicode buffers look very similar, except for the g/u property difference.

Garret Rieger 093909b2ff [subset] Fix wrong offset base for subsetting LigatureArray. 
Offsets from LigatureArray must be relative to the beginning of the LigatureArray table. For the serialization mechanism to use the correct beginning point the LigatureArray must be created using the push()/pop() mechanism. So convert LigatureArray subsetting to use serialize_subset() instead of a manually called serialize and subset.

Garret Rieger 718bf5aab3 [subset] only keep features reachable from script in the final subset. 
Matches fontTools behaviour.

Garret Rieger e583505334 [subset] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS 
This matches fontTools behaviour. glyphset_gsub does not contain gids added from closing over composite glyphs in glyf, since these cannot particpate in GSUB/GPOS processing.

Garret Rieger 940e1c6f98 [subset] ChainContextFormat3 - don't subset glyph sequences. 
The backtrack, input, and lookahead sequence must be matched in their entirety so these sequences should not be subset. If any of the coverage tables in a sequence subsets to empty then the whole subtable should be dropped since it's not possible for this lookup to be activated.

Garret Rieger 3271a7cdaa [subset] Remove redundant langys from Amiri test font. 
FontTools removes these when subsetting but harfbuzz does not yet support redundant langsys removal. So this gets the Amiri tests passing for now.

Behdad Esfahbod 48fcb9094a [docs] Remove misleading wording re OpenType 
HarfBuzz has not *just* been implementing OpenType for a while.
At least since 2.0, where we added native AAT support in Oct 2018.
