Reset scroll state on finger configuration change
When scrolling, the current code remembers how close the movement is to emitting a scroll button, in order to produce a continuous stepping motion. However, when the finger configuration on the trackpad changes, this state should start over again, or the next scolling gesture may scroll prematurely. This patch resets the scrolling state when a change is detected, which fixes the problem. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
