Matthias Clasen e7ab42b246 [layout] Fix handling of baseline variations
For BASE table format 1.1, the handling of design
space vs user space coordinates was inconsistent.
We were applying design -> user transformation
twice for the deltas, leading to wrong baseline
values.

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.

David Corbett ae9afd9772 Let BCP 47 tag "mo" fall back to OT tag 'ROM ' 2022-01-30 14:32:59 -05:00
David Corbett a184c5f851 Don’t always inherit from macrolanguages
If an OpenType tag maps to a BCP 47 macrolanguage, that is presumably to
support the use of the macrolanguage as a vague stand-in for one of its
individual languages. For example, "ar" and "zh" are often used for
"arb" and "cmn". When the OpenType tag maps to a macrolanguage and some
but not all of its individual languages, that indicates that the
OpenType tag only corresponds to the listed individual languages (which
may be referred to using the macrolanguage subtag) but not the missing
individual languages. In particular, INUK (Nunavik Inuktitut) is mapped
to "ike" (Eastern Canadian Inuktitut) and "iu" (Inuktitut) but not to
"ikt" (Inuinnaqtun), so "ikt" should not inherit the INUK mapping from
its macrolanguage "iu".

Garret Rieger 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.

Khaled Hosny fa29006bfa [doc] Fix generation of hb_glyph_flags_t docs
GTK-Doc does not like the empty lines here, and interprets everything
after the first empty line as the description of the enum itself not a
specific member and the generated text makes no sense.

Removing the empty lines makes the text harder to read (both in source
and HTML), but at least it is correctly organized.
