ImmediateInterpreter: Handle right taps that exhibit some "light" merging
We noticed on some hardware that when two fingers join or leave,
sometimes there is a frame of data that has only one contact, toward
the center of where the two are in other frames, and this contact has
very light pressure. This CL uses that very light pressure as a guage
that these frames shouldn't count toward moving a lot, since such
movement would cause a tap to look like it's not a tap.
