General fixes:
=============
-- AAT 'morx' implementation.
-
-- Return "safe-to-break" bit from shaping.
-
- Implement 'rand' feature.
-- mask propagation? (when ligation, "or" the masks).
-
-- Warn at compile time (and runtime with HB_DEBUG?) if no Unicode / font
- funcs found / set.
-
-- Do proper rounding when scaling from font space? May be a non-issue.
-
-- Misc features:
- * init/medi/fina/isol for non-cursive scripts
-
-API issues to fix before 1.0:
-============================
+API issues:
+===========
- API to accept a list of languages?
-- Add init_func to font_funcs. Adjust ft.
-
-- hb-ft load_flags issues.
-
-- Add pkg-config files for glue codes (harfbuzz-glib, etc)
-
-- 'const' for getter APIs? (use mutable internally)
-
- Remove hb_ot_shape_glyphs_closure()?
- Language to/from script.
-- blob_from_file?
-
- Add hb-cairo glue
- Add sanitize API (and a cached version, that saves result on blob user-data)
- Add query / enumeration API for aalt-like features?
-- SFNT api? get_num_faces? get_table_tags? (there's something in stash)
-
- Add segmentation API
- Add hb-fribidi glue?
===============================
- Add --width, --height, --auto-size, --ink-box, --align, etc?
-
-
-Tests to write:
-==============
-
-- ot-layout enumeration API (needs font)
-
-- Finish test-shape.c, grep for TODO
-
-- Finish test-unicode.c, grep for TODO
-
-- GObject, FreeType, etc
-
-- hb_cache_t and relatives
-
-- hb_feature_to/from_string
-- hb_buffer_[sg]et_contents
