Avoid backing store for texturemapper layers over 8192x8192
We already block too large elements from getting a composited layer with
backing store, but in the case where an already composited layer is
resized above the size limit, it may have bad size until relayed out.
This patch blocks the backing store of such a graphics layer from being
instantiated.
