General fixes:
=============
-- Instead of forming clusters immediately, only do it if we are reversing
- the text. We'd need a separate bit to indicate cluster start then.
+- Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
-- Right now, BTW, for non-native direction runs, we get the cluster wrong...
- Should do min(input-glyphs.cluster)
+- Do proper rounding when scaling from font space?
-- Fix tt kern on/off and GPOS interaction
+- Misc features:
+ * init/medi/fina/isol for non-cursive scripts
+ * vkna,hkna etc for kana, *jmo for hangul, etc
-- Do proper rounding when scaling from font space?
API issues to fix before 1.0:
============================
+- Add pkg-config files for glue codes (harfbuzz-glib, etc)
+
- Figure out how many .so objects, how to link, etc
- Add hb-cairo glue
-- Add sanitize API
+- Add sanitize API (and a cached version, that saves result on blob user-data)
+
+- hb_shape() currently does a bit more than hb_ot_shape(). Shouldn't.
- Add glib GBoxedType stuff and introspection
- ot-layout enumeration API (needs font)
+- Finish test-shape.c, grep for TODO
+
+- Finish test-unicode.c, grep for TODO
+
