SVN rev 199948 on 2009-11-29 20:48:19Z by nwhitehorn
Early-generation touchpads do not send periodic calibration frames for
baseline subtraction, and are very temperature sensitive, so would slowly
drift out of a calibrated state when under load. Escape this by taking
the last frame before we decide that the pad is idle as a finger-free
baseline.
Tested on: iBook G4
