Returns buffer glyph position array. Returned pointer
is valid as long as buffer contents are not modified.
If buffer did not have positions before, the positions will be
initialized to zeros, unless this function is called from
within a buffer message callback (see harfbuzz.global.bufferSetMessageFunc),
in which case NULL is returned.
