Qunxin Liu 8eadb83640 [subset] Update hb_subset_input_override_name_table API
Override the name string for the NameRecord identified by name_id,
platform_id, encoding_id and language_ids specified by the user.
If a record with specified name_id does not exist, this API will create
a new NameRecord with provided info and insert it to the name table.

Frédéric Wang 03d2376745 [math] Improve fuzzing coverage
Extend testing to cover parts that are missing according to the recent
oss-fuzz-coverage report:
- Retriving all constants from MathConstants.
- Retrieving entries from MathKern, MathGlyphPartRecord and
  MathGlyphAssembly.
- Retrieving italic correction from MathGlyphAssembly.
- Choosing between horizontal/vertical offset in MathVariants.

Garret Rieger af74ab452f [repack] always run the sort in repack.
This is needed to ensure virtual link ordering constraints are respected when repack is being called from fontTools. For subset usage, repack won't be called if the graph doesn't already overflow so this change doesn't cause any extra work.

Matthias Clasen f81578fd86 [ot-layout] Synthesize missing baselines
Add a variation of hb_ot_layout_get_baseline that
synthesizes missing baselines, using heuristics in part
taken from the CSS Inline Layout Module, Level 3.

Includes some new tests for synthesized baselines.
The base2.ttf is a subset of Noto Sans Bengali that
includes just the Bengali Ka.

New API: hb_ot_layout_get_baseline_with_fallback

[Boring Expansion] >64k loca & hmtx tables

This does two things:

The num-glyphs reported by the face now is the maximum reported by the maxp and that deduced from the length of the loca table; I think this is the right thing to do anyway; According to OpenType such loca tables are invalid.

The interpretation hmtx tables that have excessive bytes at the end, again, invalid according to OpenType, has changed. Previously we were interpreting those excessive bytes as extra lsb values. Now we interpret them as extra advance values, the last of which is repeated for all missing glyphs. Again, these are tables that are invalid according to OpenType, and the advances are for glyph indices beyond maxp table's num-glyphs.

The combined effect is that the font can have shapes and advances for gid's beyond the maxp limit of 64k. In fact, maxp table becomes optional.

Ebrahim Byagowi 6b75a30a73 [draw/test] Swap a freetype test case with a simpler one
As CI failure, apparently the my local freetype and CI one have different
result so let's switch the case with a simpler one just to test quadratic command
is emitted correctly.

This is unnecessary overhead. Up to rasterizers to handle this.  Plus,
