On some touchpads, the pointer keeps +moving in the last direction when the finger movement stops but the finger +is left on the touchpad. + +Cause appears to be get_delta() which calculates the deltas based on the +motion history but has no control flow for the lack of fake motion events +in the history after this commit.
