   [[Widget container that allows objects bigger than itself to be put inside it, and provides
     scrolling functionality so the whole content is visible.
   
     Some widgets have scrolling capabilities (like @Efl.Ui.List) that allow big content
     to be shown inside a small viewport, using the well-known scrollbar objects.
     Some other widgets (like @Efl.Ui.Box, for example) cannot scroll by themselves and
     therefore would not be fully visible when placed inside a viewport smaller than them.

     The @Efl.Ui.Scroller is a helper class that provides scrolling capabilities for widgets
     which don't have them. In the above example, simply putting the @Efl.Ui.Box inside a
     @Efl.Ui.Scroller (using @Efl.Content.content.set) would give it the ability to scroll.
