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

Matthias Clasen 16b232be0e [hb-style] Fix the sign of slant ratios
We want negative slant angles to yield
positive slant ratios. Fix that.

Test included.

Matthias Clasen 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.

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.

Ebrahim Byagowi 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.

Behdad Esfahbod 1740916ede [draw] Remove check for no-op
This is unnecessary overhead. Up to rasterizers to handle this.  Plus,
this throws off point-numbers in uses that rely on it.

Add the ability to create a subset plan which an be used to gather info on things like glyph mappings in the final subset. The plan can then be passed on to perform the subsetting operation.

Instead use inverted sets to handle requesting all features. Modifies feature collection in subset plan to intersect the set of requested features against the features in the font. This prevents iterating a fully filled feature tag set.
