    A Flickable that can be put in front of the item to be flicked and
    still have the item-to-be-flicked receive input events that are not flicks.

    Ie, it's a Flickable that, input-wise, is transparent to non-flick gestures.

    With a regular Flickable you would have to make the item-to-be-flicked a child
    of Flicakble to achieve the same result. FloatingFlickable has no such requirement
    or limitation.
