	e8139bea	2024-03-27T11:39:32		Revert "[varc] Reuse x_deltas and y_deltas vectors" This reverts commit 604f27b3069f2ef11b045cfb35e8c3a5fd99fb8b. Not worth it.
	f97d1ea2	2024-03-27T11:38:58		[varc] Reuse x_deltas and y_deltas vectors Going to revert since it has minimal improvement with lots of piping through.

	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.

	09386737	2023-04-26T13:19:27		[gvar] Error handling & micro-optimization
	b6aa2d71	2023-04-26T13:06:24		[gvar] Speed up calculate_scalar more Use a gvar-wide cache of the one active peak index for shared-tuples that have only one active peak. This speeds up the scalar calculation. This shows significant speedup for the CJK VarComposite font for example since that has tens of axes with mostly only one active peak.

	20454eaa	2023-04-24T15:50:58		[gvar] Optimize by applying deltas in batches Shows up to 7% speedup in one of my benchmarks. One test fails by one rounding issue. To be updated.
	491aa572	2023-04-24T15:05:18		[gvar] Minor call a function instead of handcoding
	552290f6	2023-03-08T10:25:26		[gvar] Fix out-of-memory access issue Fixes https://oss-fuzz.com/testcase-detail/5953342850596864
	ea17c7a8	2023-03-07T14:23:39		[beyond-64k] Implement gvar support https://github.com/harfbuzz/boring-expansion-spec/issues/85
	22cc73f3	2023-02-06T12:36:05		Move common structs for TupleVariation from gvar to var-common.hh Also added a table_base in the iterator and related function to handle different start address for dataoffset in cvar and gvar
	c8486b63	2023-01-07T14:15:17		[open-type] Add to_int to fixed types To make sure we don't accidentally forget to_float(). As we did recently in COLRv1 code.
	8e468700	2022-12-09T18:35:30		[gvar] Take coords in instead of font in apply_deltas_to_points

	a3830272	2022-11-22T14:15:17		[gvar] Cosmetic
	be89919a	2022-11-22T13:56:20		[gvar] is_valid() remove a check I don't know why this check was there, but it doesn't make sense because that function never returns 0 / false.
	e8ddf107	2022-11-22T13:29:32		[gvar] Optimize a loop
	dd6fcec9	2022-11-22T13:27:40		[gvar] Remove a conditional
