This has changed in trunk to ProcessAckedTouchEvent. Note that touch-events can
now be coalesced, and when that happens, the number of ACKs won't be the same as
the number of ForwardTouchEvent() calls made. I don't know what
ConfirmTouchEvent() does (or where it used to be called before this changed), so
this may not be an issue. But I wanted to point this out.

Ya, Android might still need to be further updated after your changes. It's
passed into our GestureHandler which I believe does some of the same work so we
can probably re-use more of your changes.
