4 - Move feature parsing from util into the library
6 - 'const' for getter APIs? (use mutable internally)
8 - Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
10 - Do proper rounding when scaling from font space?
13 * init/medi/fina/isol for non-cursive scripts
14 * vkna,hkna etc for kana, *jmo for hangul, etc
16 - Move non-native direction and normalization handling to the generic non-OT
17 layer, such that uniscribe and other backends can use.
19 - Uniscribe backend needs to enforce one direction only, otherwise cluster
20 values can confused the user.
23 API issues to fix before 1.0:
24 ============================
26 - Rename all internal symbols (static ones even) to have _hb prefix?
28 - Add pkg-config files for glue codes (harfbuzz-glib, etc)
30 - Figure out how many .so objects, how to link, etc
34 - Add sanitize API (and a cached version, that saves result on blob user-data)
36 - Add glib GBoxedType stuff and introspection
39 API to add (maybe after 1.0):
40 ============================
42 - Add Uniscribe face / font get API
44 - BCP 47 language handling / API (language_matches?)
46 - Add hb_face_get_glyph_count()?
48 - Add hb_font_create_linear()?
50 - Add hb_shape_plan()/hb_shape_execute()
52 - Add query API for aalt-like features?
54 - SFNT api? get_num_faces? get_table_tags? (there's something in stash)
56 - Add segmentation API
65 - Add --width, --height, --auto-size, --align, etc?
66 - Port to GOption, --help
67 - Add XML and JSON formats
73 - ot-layout enumeration API (needs font)
75 - Finish test-shape.c, grep for TODO
77 - Finish test-unicode.c, grep for TODO
83 - Avoid allocating blob objects internally for for_data() faces?
85 - Add caching layer to hb-ft
