d4cb07728c Add a missing file 
The style test is using notosansitalic.ttf now,
but I forgot to add it with the test. Fix that.

e76061a737 [hb-style] Fix synthetic slant values 
When reporting the slant ratio of a font
that has synthetic slant set, we were
reporting twice the expected value.
Fix that. Test included.

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

Merge pull request #3410 from harfbuzz/boring-expansion 
[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.

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.

d4588204e5 [draw/glyf] Emit empty contours 
This makes it actually match freetype behaviour even though rasterizer
should filter such contours specially for stroking.

See https://github.com/harfbuzz/harfbuzz/pull/3411#discussion_r802283827 for the context.

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

bc899650c7 [subset] Fix for issue #3397. 
cur_intersected_glyphs gets modified during recursion leading to incorrect filtering of sub tables in some cases. So don't use cur_intersected_glyphs. Instead just add an additional entry onto the parent_active_glyphs () stack.

Additionaly expands NotoNastaliqUrdu tests to include coverage of the issue from #3397.
