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.

Fix unintentional locale dependency (#3358)
Avoid unintentional locale dependency

hb_variation_to_string uses sprintf with %g, which will produce
a locale-dependent decimal point, which is not desired here.

The output is supposed to be compatible with CSS syntax, and
that always uses '.' for the decimal point.

Fix this by changing the per-thread locale to "C" around sprintf call.

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.
