Behdad Esfahbod 93e6a9bc4e Revert "Remove unneeded buffer clear_output / remove_output calls"

Behdad Esfahbod 06175b7143 Remove unneeded buffer clear_output / remove_output calls 
Made sure clear_output is always paired with swap_buffers.
Trying to see if we can move towards RAII-like buffer iterators
instead of the buffer keeping an iterator internally.

Behdad Esfahbod cd65305b05 [config] Don't disable emoji sequences in HB_TINY 
It makes sense to disable this code these if editing is not needed.
However, this is also necessary to correctly display emoji sequences
in right-to-left direction.  For that reason, don't auto-disable it.
