Sets @self to be homogeneous or not. If it is homogeneous, @self will request
the same size for all its children for its opposite orientation, e.g. if
@self is oriented horizontally and is homogeneous, it will request the same
height for all its children. If it isn't, @self may change size when a
different child becomes visible.
