Adobe, Inc has copyright in src/hb-subset-cff*, test/api/test-subset*, and
misc other places.
Ebrahim Byagowi has copyright as far back as 2015 in places like
src/hb-directwrite.cc.
Google, Inc has newer copyright into 2022 in places like
src/graph/test-classdef-graph.cc. Also, listing every year was getting a bit
unwieldy, so just do 2010-2022.
Igalia S.L. contributed the stuff in src/hb-ot-math*.
The only references I could find to Martin Hosken & SIL were in
src/hb-graphite2*, and they were 2011, not 2009.
Mozilla's got a bunch of 2015 code in src/hb-ot-shaper-*.
Red Hat has copyright up to 2023 (eg, test/api/test-glyph-names.c).
