ae9afd9772 Let BCP 47 tag "mo" fall back to OT tag 'ROM ' 2022-01-30 14:32:59 -05:00

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".

0e31595e0d Infer tag mappings for unregistered macrolanguages 
Every macrolanguage not mentioned in the OT language system tag registry
is mapped to every tag of its individual languages, if those have
registered tags.

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.

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.
