There really isn't a point to scrolling while a clickpad is pressed. In
particular, the clickpad button areas and the horizontal edge scrolling
areas overlap, so horizontal edge scrolling must be disabled. Also,
performing two finger scrolling while a third finger presses the button
would require us to inhibit touch events until four touches are present.
That is enough reason to disable two finger scrolling as well.
