Garret Rieger b65e48a786 [subset] Add subset plan to public API.
Add the ability to create a subset plan which an be used to gather info on things like glyph mappings in the final subset. The plan can then be passed on to perform the subsetting operation.

Behdad Esfahbod ac1bb3e39e [machinery] Move accelerators to constructor/destructor 2022-01-20 12:10:05 -07:00
Behdad Esfahbod e062376ef1 [machinery] Make accelerator lazy-loader call Xinit/Xfini
Instead of init/fini. To isolate those functions. To be turned into
constructor/destructors, ideally one per commit (after some SFINAE
foo.)

Behdad Esfahbod 394f772937 [map] Allow storing classes in the hashmap
Fixes https://github.com/harfbuzz/harfbuzz/issues/3293

The trick was to change the type of the invalid key/value to be non-class.

Garret Rieger 8f4f47df7c [subset] use inverted set for all unicodes.
Modify the code that handles input->unicodes to be safe with possibly inverted sets. Also adds --unicodes-= and --unicodes+= flags.

Garret Rieger f2441a4b65 [subset] Remove retain all layout features flag.
Instead use inverted sets to handle requesting all features. Modifies feature collection in subset plan to intersect the set of requested features against the features in the font. This prevents iterating a fully filled feature tag set.

Garret Rieger a08900b721 [subset] fix failing colrv0 subsetting when font has composite glyphs.
Composite glyph collection was happening along side colrv0 glyph collection which meant it was possible to miss grabbing the component glyphs for a glyph added by colrv0.

Qunxin Liu 56ca435787 [subset] fix for collect_features and remove_redundant_lamngsys
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.
