New minor version.

[Xi Ruoyao]

There is a test failure: ​https://github.com/harfbuzz/harfbuzz/issues/3684

Not sure if we need to pull the fix in.

This looks like it is fixed upstream. Let's wait a couple of days to see if a new version is released.

Overview of changes leading to 4.4.0 - Monday, June 27, 2022

• Caching of variable fonts shaping, in particular when using HarfBuzz’s own font loading functions (ot). Bringing performance of variable shaping in par with non-variable fonts shaping.
• Caching of format 2 “Contextual Substitution” and “Chained Contexts Substitution” lookups. Resulting in up to 20% speedup of lookup-heavy fonts like Gulzar or Noto Nastaliq Urdu.
• Improved ANSI output from hb-view.
• Support for shaping legacy, pre-OpenType Windows 3.1-era, Arabic fonts that relied on a fixed PUA encoding.
• Sinhala script is now shaped by the USE shaper instead of “indic” one.
• Thai shaper improvements.
• hb-ot-name API supports approximate BCP-47 language matching, for example asking for “en_US” in a font that has only “en” names will return them.
• Optimized TrueType glyph shape loading.
• Fix subsetting of HarfBuzz faces created via hb_face_create_for_tables().
• Add 32 bit var store support to the subsetter.

• New API
