4 - Instead of forming clusters immediately, only do it if we are reversing
5 the text. We'd need a separate bit to indicate cluster start then.
7 - Right now, BTW, for non-native direction runs, we get the cluster wrong...
8 Should do min(input-glyphs.cluster)
10 - Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
12 - Do proper rounding when scaling from font space?
15 * init/medi/fina/isol for non-cursive scripts
16 * vkna,hkna etc for kana, *jmo for hangul, etc
19 API issues to fix before 1.0:
20 ============================
22 - Add pkg-config files for glue codes (harfbuzz-glib, etc)
24 - Figure out how many .so objects, how to link, etc
28 - Add sanitize API (and a cached version, that saves result on blob user-data)
30 - hb_shape() currently does a bit more than hb_ot_shape(). Shouldn't.
32 - Add glib GBoxedType stuff and introspection
35 API to add (maybe after 1.0):
36 ============================
38 - BCP 47 language handling / API (language_matches?)
40 - Add hb_face_get_glyph_count()?
42 - Add hb_font_create_linear()?
44 - Add hb_shape_plan()/hb_shape_execute()
46 - Add query API for aalt-like features?
48 - SFNT api? get_num_faces? get_table_tags? (there's something in stash)
50 - Full matrix instead of scale?
52 - Add segmentation API
61 - Add --width, --height, --auto-size, --align, etc?
62 - Port to GOption, --help
63 - Add XML and JSON formats
69 - ot-layout enumeration API (needs font)
77 - Avoid allocating blob objects internally for for_data() faces?
79 - Add caching layer to hb-ft
