Right now, the supported scripts are Hebrew, Latin, Greek, and
Cyrillic.  For Hebrew, I've extended the auto-hinter to align along
the long horizontal features, ignoring the top `bumps' usually seen in
many fonts.

It's trivial to add more scripts that have a similar optical structure
as Latin (e.g. Armenian).  [`Trivial' means about 20 minutes of work.]
However, I want to first get user reports whether everything works as
expected.  Additionally, integration of HarfBuzz has a higher
priority.

Below you can see the currently defined blue zones (some of them used
for both top and bottom zones).
