    Allow 0 as wheel emulation button for unconditional scrolling (#20529)
    
    If wheel emulation is on and the emulation button is 0, then any x/y motion
    of the device is converted into wheel events. The devices becomes a
    scrolling-only device.

    Restrict wheel emulation to a single axis at a time.
    
    Wheel emulation works for both horizontal and vertical axes. Thus, if a
    device doesn't move in perfect straight line, scroll events build up on the
    respective other axis.
    
    In some clients, scroll wheel events have specific meanings other than
    scrolling (e.g. mplayer). In these clients, erroneous scrolling events come
    at a high cost.
    
    Thus, if a scroll wheel event is generated for one axis, reset the inertia
    of the other axis to 0, avoiding the buildup of these erroneous scrolling
    events.
