> We can make non-ContainerNodes (Text mostly) smaller by moving the tree scope pointer from Node to ContainerNode. Non-containers can get it from the parent (and they don't need it much anyway).

Note also that "they don't need it much anyway" is not really true since document() goes through m_treeScope and CharacterData.cpp uses document() a bunch; Text.cpp also uses it in the critical path for recalcTextStyle and RenderText.cpp also uses document() in a bunch of performance sensitive places.
