------- Additional Comments from Huang Dongsung <luxtella at company100.net>
Turn on r? because code is little changed.

Previous patch added following assertion.
+    ASSERT(layerID != m_rootLayerID);
+    ASSERT(layerID != InvalidWebLayerID);

This patch added following assertion.
+    ASSERT(layerID != InvalidCoordinatedLayerID);
+    ASSERT(m_rootLayerID == InvalidCoordinatedLayerID);

This assertion is more strict.
