In bug 1128658 HarfBuzz have found a bug that affects Devanagari text layout with Arial Unicode MS, maybe waiting for HarfBuzz 1.2.8 or higher would be better.

Attachment: Update harfbuzz to release 1.3.0 + additional recent fixes from upstream

Routine update to pick up latest improvements (see issues mentioned above). I've pulled the latest trunk code from upstream, rather than the actual 1.3.0 release, as there are a few additional post-1.3.0 fixes that seem worth taking at the same time.
