    main: Use the seat pointer device for touchpad gesture events
    
    In cab1dcb6960d1efb4dee916a1c804c908664c530, events stopped carrying around
    a separate source device, and instead the seat pointer is always used as
    the device for scroll events. However, this is also relevant for touchpad
    gesture events and they are ignored otherwise.
