LibGUI: Add layout change propagation to Widget

Browse source 
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.
