Hi -- I'm curious to know about your future plans for Indic. Are you
going to use HarfBuzz? Even in Indic, I have specific minority
orthography requirements due to which I'm using Graphite-enabled
fonts. HarfBuzz (new one, not old one) supports Graphite and so my
requirements would be met if that is used, but if you are going to
develop yet another rendering system (please don't tell me it's so) it
would be quite difficult...
