[PATCH v2 0/3] input: appletouch: fixes for jagged/uneven cursor movement

These patches address some usability issues by dialing back the fuzz and threshold parameters, by implementing some smoothing for the sensor data and by discarding movements that directly coincide with a change in the number of fingers detected on the touchpad.

Changes since last time:

1/3: Remove extraneous cleanup - I'll submit a separate patch another day
2/3: Apply smoothing to the sensor data before position calculation, eliminating the need to toss values based on a threshold; simplify formula for averaging with prior values
