[HarfBuzz] Hebrew shaper

[Behdad Esfahbod]

Hi Dov,

As I'm developing HarfBuzz to replace the shapers in Pango I'm planning on
removing the Hebrew fallback shaping functionality that is in Pango.  Can you
confirm that the fallback shaping functionality is obsolete and not needed
with Hebrew fonts in wide circulation these days?

If it *is* needed still, can you offer any help?  I have a plan for
implementing such fallback shapers but appreciate a helping hand.

Cheers,
behdad
