Issue: Touch panel filtering does not reset on non-touch (Closed: Fixed)

Touch one area of the screen long enough for the filter to produce data. Remove that touch and touch elsewhere.

What seems to happen is that the filter is not reset by the non-touch. So, the first few points at the old location can be part of the computation and you get a reported touch that is between the two locations.

Possible solution - add a timer, and reset if some period of time without a touch.
