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...

- Fix tt kern on/off and GPOS interaction

API issues to fix before 1.0:
============================

- Figure out how many .so objects, how to link, etc

- Real subclassing support for vfunc vectors

- Add hb-cairo glue

- Fix blob, remove mutex, etc.

- Add sanitize API

- Add glib GBoxedType stuff


API to add (maybe after 1.0):
============================

- Add hb_font_create_linear()?

- Add hb_shape_plan()/hb_shape_execute()

- Add query API for aalt-like features?

- SFNT api? get_num_faces?

- Full matrix instead of scale?

- Add segmentation API

- Add hb-fribidi?


hb-view enhancements:
====================

- Add --format
- Add --width, --height, --auto-size, --align, etc?
- Port to GOption, --help
- Add XML and JSON formats


Optimizations:
=============

- Avoid allocating blob objects internally for for_data() faces?

- Add caching layer to hb-ft
