SecondDisplayController called native code and woke the app thread's
looper once per finger for every MotionEvent. The pointers now go into
a direct buffer shared with native code, packed as VIDEO_POS_PACK
positions, and one nativeTouches() call reads them in place and wakes
the looper once. The ring's records carry the packed position the poll
stores, so it no longer packs them.
