bb7b634cd0 Simplify JSON unicode serialization 
It’s just an array of codepoints; no need to turn them into objects

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.

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.

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.

a5c0ec7516 [subset] For [Chain]ContextFormat3 make sure the sub table intersects the retained glyphset before recursing to its lookups. 
Otherwise the lookup closure will potentially pull in lookups which cannot be accessed via the retained glyph set.

dc375559fd [subset] shrink the serialize buffer when pruning empty offsets in ChainContextFormat2. 
Currently the code reduces the array length, but does not trim back the space allocated in the serializer for those empty offsets.

90eb1a40eb [subset] In ChainContextFormat3 don't skip subsetting if backtrack or lookahead are empty. 
It's valid to have a ChainContextFormat3 with either an empty backtrack or lookahead. Only drop the lookup if the input sequence is empty.

2604201ae0 src/meson.build: allow introspection when cross-compiling 
introspection can be enabled when cross-compiling on certains conditions
(for example it is supported by buildroot) so, as suggested by
Tim-Philipp Müller, disable it by default for cross builds unless the
option was explicitly enabled by the user

[ENOMEM] Return gracefully if stages isn't initialized correctly (#2639) 
This happens if calls to 'm.lookups[table_index].push ()' has been
silently failed due to lack of memory.

This change just returns gracefully instead issuing the assert.

e40c0d82e2 [ENOMEM] Handle immutable buffer in shape_full() 
Move the content_type changing to shape_plan_execute() where it belongs.
Skip setting if content type is UNKNOWN, which happens with empty buffers
only, including the immutable buffer.

f3929abafe [ENOMEM] don't perform set process operations if the other set is in an error state. 
Running a process while the other set is in an error state can potentially corrupt this sets map map (for example by overwritting all of the major values with 0).

Uniscribe enables it by default.
