    gdk: update csw event mask filter to handle smooth scroll
    
    Events of type GDK_SCROLL will be received if the client side window
    event mask has either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK.
    
    GDK_BUTTON_PRESS_MASK has been removed from type_masks[GDK_SCROLL]
    as that bit is often set for other-than-scrolling purposes, and
    yet have the window receive scroll events. In GTK+, this forces
    non-smooth events bubbling, even if the widgets above want smooth
    events, and legitimately set GDK_[SMOOTH_]SCROLL_MASK.
