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?
14 - Adjust default features for vertical text:
16 * vrt2 preferred over vert; but if user selects vert, turn vrt2 off?
17 * vkrn (enables vpal? vpal anyone???);
18 * valt: "This feature is mutually exclusive with all other glyph-height features (e.g. vhal and vpal),
19 which should be turned off when it's applied. It deactivates the kern."
22 API issues to fix before 1.0:
23 ============================
25 - Figure out how many .so objects, how to link, etc
29 - Add sanitize API (and a cached version, that saves result on blob user-data)
31 - hb_shape() currently does a bit more than hb_ot_shape(). Shouldn't.
33 - Add glib GBoxedType stuff and introspection
36 API to add (maybe after 1.0):
37 ============================
39 - BCP 47 language handling / API (language_matches?)
41 - Add hb_face_get_glyph_count()?
43 - Add hb_font_create_linear()?
45 - Add hb_shape_plan()/hb_shape_execute()
47 - Add query API for aalt-like features?
49 - SFNT api? get_num_faces? get_table_tags? (there's something in stash)
51 - Full matrix instead of scale?
53 - Add segmentation API
62 - Add --width, --height, --auto-size, --align, etc?
63 - Port to GOption, --help
64 - Add XML and JSON formats
70 - ot-layout enumeration API (needs font)
78 - Avoid allocating blob objects internally for for_data() faces?
80 - Add caching layer to hb-ft
