Note
1: P is the proximity bit. It is set to 1 when there is a touch, 0 for a liftoff.
The ID is associated with a touch stream from one finger. The ID, in the range of 0-127,
is assigned on a rotating basis at touchdown.
A finger touch stream consists of a
touchdown, maybe some continuing touch points, ending with a liftoff. The ID is
released on liftoff, and becomes available to be reassigned.
When multiple fingers are down, the packets from the touch streams are sent interleaved.
There is no order imposed on the interleave.
