> 	- A new API have been added to pre-process the face and speed up future
> 	  subsetting operations on that face. Provides up to a 95% reduction in
> 	  subsetting times when the same face is subset more than once.
> 	  For more details and benchmarks, see:
> 	  https://github.com/harfbuzz/harfbuzz/blob/main/docs/subset-preprocessing.md
> 	- Shaping have been speedup by skipping entire lookups when the buffer contents
> 	  don't intersect with the lookup. Shows up to a 10% speedup in shaping some
> 	  fonts. (Behdad Esfahbod)
> 	- A new experimental feature, “Variable Composites” (enabled by passing
> 	  -Dexperimental_api=true to meson), is also featured in this release.
> 	  This technology enables drastic compression of fonts in the Chinese,
> 	  Japanese, Korean, and other writing systems, by reusing the OpenType Font
> 	  Variations technology for encoding “smart components” into the font.
> 	  The specification for these  extensions to the font format can be found in:
> 	  https://github.com/harfbuzz/boring-expansion-spec/blob/glyf1/glyf1.md
> 	  A test variable-font with ~7160 Hangul syllables derived from the
> 	  NotoSerifKR-VF font has been built, with existing OpenType technology, as
> 	  well as with the new Variable Composites (VarComposites) technology. The
> 	  VarComposites font is over 90% smaller than the OpenType version of the font!
> 	  Both fonts can be obtained from the “smarties” repository:
> 	  https://github.com/behdad/smarties/tree/3.0/fonts/hangul/serif
> 	  When building HarfBuzz with experimental features enabled, you can test
> 	  the “smarties” font with a sample character like this:
> 	  $ hb-view butchered-hangul-serif-smarties-variable.ttf -u AE01 --variations=wght=700
> 	- The HarfBuzz subsetter can now drop axes by pinning them to specific values
> 	  (also referred to as instancing). There are a couple of restrictions
> 	  currently:
> 	  - Only works with TrueType (“glyf”) based fonts. “CFF2” fonts are not yet
> 	    supported.
> 	  - Only supports the case where all axes in a font are pinned.
> 	- Miscellaneous fixes and improvements.
> 	- New API
> 		+hb_subset_input_pin_axis_location()
> 		+hb_subset_input_pin_axis_to_default()
> 		+hb_subset_preprocess()
>     Overview of changes leading to 5.3.1
> 	- Subsetter repacker fixes. (Garret Rieger)
> 	- Adjust Grapheme clusters for Katakana voiced sound marks. (Behdad Esfahbod)
> 	- New “hb-subset” option “--preprocess-face”. (Garret Rieger)
>     Overview of changes leading to 5.3.0
> 	- Don’t add glyphs from dropped MATH or COLR tables to the subset glyphs.
> 	  (Khaled Hosny)
> 	- Map “rlig” to appropriate AAT feature selectors. (Jonathan Kew)
> 	- Update USE data files to latest version. (David Corbett)
> 	- Check “CBDT” extents first before outline tables, to help with fonts that
> 	  also include an empty “glyf” table. (Khaled Hosny)
