Too much scrolling down may eventually trigger an overflow of the valuator. If this happens, reset the valuator to 0 and skip this event for button emulation. Clients will have to figure out a way to deal with this, but a scroll event from (close to) INT_MAX to 0 is a hint of that it needs to be ignored.
