23  A Flickable that can be put in front of the item to be flicked and
24  still have the item-to-be-flicked receive input events that are not flicks.
25 
26  Ie, it's a Flickable that, input-wise, is transparent to non-flick gestures.
27 
28  With a regular Flickable you would have to make the item-to-be-flicked a child
29  of Flicakble to achieve the same result. FloatingFlickable has no such requirement
30  or limitation.
