IMHO, if we want to ship this by default, we really need to fix FreeType for
the case where the font doesn't provide hinting bytecode. AFAICT, currently,
in that case, if FreeType is built with the BCI enabled, it won't do any
hinting at all. See e.g. the CJK characters in the screenshot by Martin
Sourada at:

(the first line is no antialiasing, no hinting, the second one is
antialiasing only, the third one is antialiasing+hinting and the last one is
antialiasing+hinting with forced autohinter)
from:

It should fall back to the autohinter when the font does not provide hinting
bytecode.
