Patch 3/7 isn't actually adding this, it just modifies the lines to
simplify touch data bit manipulation. Keeping this as a separate commit
ensures we maintain independent changes separately. As it is, Patch 3/7
doesn't actually change any functionality. If this were folded in, it
would change the functionality in an otherwise nop commit.
