docs: The size of the ViewPort (virtual area used by the list rendering engine)
  If {@link Layout#mViewPort} is set to true the ViewPort is applied during layout.
  The unlimited size can be specified for the layout.
  
  @param enable true to apply the view port, false - otherwise, all items are rendered in the list even if they
  occupy larger space  than the container size is.
