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.
-
-- Right now, BTW, for non-native direction runs, we get the cluster wrong...
- Should do min(input-glyphs.cluster)
-
- Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
- Do proper rounding when scaling from font space?
-- Adjust default features for vertical text:
-
- * vrt2 preferred over vert; but if user selects vert, turn vrt2 off?
- * vkrn (enables vpal? vpal anyone???);
- * valt: "This feature is mutually exclusive with all other glyph-height features (e.g. vhal and vpal),
- which should be turned off when it's applied. It deactivates the kern."
+- Misc features:
+ * init/medi/fina/isol for non-cursive scripts
+ * vkna,hkna etc for kana, *jmo for hangul, etc
API issues to fix before 1.0:
- ot-layout enumeration API (needs font)
-- Finish test-shape.c
+- Finish test-shape.c, grep for TODO
+
+- Finish test-unicode.c, grep for TODO
