The most important change is that we now use HarfBuzz by default.

Richard didn't contribute the Tai Tham composition rules to us
(AFAIR), so I cannot test what happens now in Emacs with HarfBuzz.
Maybe we should revisit this issue, but first I hope Richard could
tell whether the issue still exists, and if so, what composition rules
he uses or suggests to use for Tai Tham.
