Until now, paint trees have been piggybacking on the layout tree for traversal, and paintables didn't actually have their own parent/child pointers. This patch changes that by making Paintable inherit from TreeNode, and adding a new pass to LayoutState::commit() where we recursively build the new paint tree.
