Garret Rieger 067f90a820 [subset] Fix for fuzzer timeout.
Fixes https://oss-fuzz.com/testcase-detail/5549945449480192

In prune_langsys: move LangSys visited check up before any work is done for a LangSys. In this particular case the compare() method is responsible for the majority of the time spent and wasn't being guarded with a visisted check.

Khaled Hosny 449c4296a1 [ci] Try harder to fix this randomly failing job
The default --num-processes is the number of CPUs multiplied by 5,
which seems to give this VM a hard-time. Even the number of CPUs is too
much, so lets use half of that (I’m adding one just in case the division
gives zero).

Garret Rieger 5914acb3cb [repacker] Clear distance and position cache when assigning a new space.
A change in space will effect the distance assigned to the node and any of it's children so clear the distance cache.

Qunxin Liu 706014f69d [subset] (Chain)ContextSubst glyph_closure fix
- When pos_glyphs is empty, use current full glyphs set as input for
subsequent recursive closure process
- Also increase max_lookup_visit_count to 35000 cause a real font file hit
previous limit 20000 and some lookups are dropped unexpectedly

Garret Rieger 441877f56a [repacker] add test case for using max priority to resolve an overflow. 2021-12-09 17:46:52 -07:00
Garret Rieger be2c488e5d [repacker] Improve vertex priority packing.
Previous priority implementation would move a node further back within it's layer, but at max priority was unable to move any further up than that. This updates the implementation to have 3 priority levels:
1. Distance is reduced by half of table size.
2. Distance is reduced by full table size (move to beginning of the layer).
3. Distance is set to 0. Vertex will be packed as soon as possible.

Also makes the iterative resolutions aware of max priority, so it won't keep trying to raise priority beyond the maximum.

Garret Rieger 3e4a25098d [repacker] add a maximum number of roots that can be moved in one iteration.
Set to half of the roots in a space. This prevents the repacker from moving all roots in a space to a new space if their are overflows in every root.

Garret Rieger 9121ed0cec [subset] Improve sharing of Ligature subtables.
Ligature subtables use virtual links to enforce an ordering constraint between the subtables and the coverage table. Unfortunately this has the sideeffect of prevent the subtables from being shared by another Ligature with a different coverage table since object equality compares all links real and virtual. This change makes virtual links stored separately from real links and updates the equality check to only check real links. If an object is de-duped any virtual links it has are merged into the object that replaces it.
