	e079dd20	2024-07-01T09:36:19		[instancer] remove the warning for CFF partial instancing Don't print from the library
	0e1ffd77	2024-05-07T13:55:03		[instancer] add a warning for CFF partial instancing It's not supported yet
	1cb47eff	2024-02-06T14:49:31		Rename VariationStore to ItemVariationStore
	9701b002	2023-11-06T22:14:31		[subset] Always place CFF1/2 char strings at the end of the packed table. Makes the behaviour from HB_SUBSET_FLAGS_IFTB_REQUIREMENTS the default.
	c6884377	2023-11-06T20:21:46		[subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2. This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.
