+ Do not modify the composited layer backing's internal layer structure directly
+ when the clipping behaviour changes.
+
+ When we directly create/destroy RenderLayerBacking::m_ancestorClippingLayer to
+ reflect the new clipping state, other, depending layers need updating. In order to
+ not to corrupt the internal hierarchy, mark the compositing layers dirty and let
+ the normal updating mechanism take care of creating/destroying the ancestor layers.
