This function is intended to propagate layout changes upwards in the widget hierarchy. Widgets that can know what to do with this information without causing a full layout invalidation (i.e. just because one of their child widgets changed layout/size, doesn't necessairily mean that they have to change their layout/size) can override this and prevent a full relayout and redraw.
