        The value can be used in two cases: <p>
        - when selectedTakesMoreSpace is true:  ScrollAdapterView will allocate more
        spaces surrounding the focused item.  The extra spaces is added to start/end
        depending on "scrollItemAlign". <p>
        - when selectedTakesMoreSpace is false: ScrollAdapterView will not allocate
        more spaces for focused item,  but will align the focused item using the value. <p>
        In any case, ScrollAdapterView never scale the View or change its width or height,
        the view itself is responsible doing the scale in ScrollAdapterTransform or
        ScrollAdapterView.OnScrollListener
