4 - Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
6 - Do proper rounding when scaling from font space?
9 * init/medi/fina/isol for non-cursive scripts
10 * vkna,hkna etc for kana, *jmo for hangul, etc
13 API issues to fix before 1.0:
14 ============================
16 - Add pkg-config files for glue codes (harfbuzz-glib, etc)
18 - Figure out how many .so objects, how to link, etc
22 - Add sanitize API (and a cached version, that saves result on blob user-data)
24 - hb_shape() currently does a bit more than hb_ot_shape(). Shouldn't.
26 - Add glib GBoxedType stuff and introspection
29 API to add (maybe after 1.0):
30 ============================
32 - BCP 47 language handling / API (language_matches?)
34 - Add hb_face_get_glyph_count()?
36 - Add hb_font_create_linear()?
38 - Add hb_shape_plan()/hb_shape_execute()
40 - Add query API for aalt-like features?
42 - SFNT api? get_num_faces? get_table_tags? (there's something in stash)
44 - Full matrix instead of scale?
46 - Add segmentation API
55 - Add --width, --height, --auto-size, --align, etc?
56 - Port to GOption, --help
57 - Add XML and JSON formats
63 - ot-layout enumeration API (needs font)
65 - Finish test-shape.c, grep for TODO
67 - Finish test-unicode.c, grep for TODO
73 - Avoid allocating blob objects internally for for_data() faces?
75 - Add caching layer to hb-ft
