Disambiguation between multiple pointers and swipe gestures.
Sometimes quickly touching the screen with two fingers will result
in the firmware thinking one finger moved very quickly. This code
tries to identify the difference between the two based on velocity
of the last N points versus the velocity of the last M points and
figure out if there was mostly acceleration or a sudden deceleration.
It's still not perfect and very dependent on the touch hardware.
