Reviewed by Dean Jackson.
CoreAnimation doesn't add a new use-count to CAIOSurfaces until the transaction
is committed, which is after the MachSendRight (inside
LayerTreeTransaction/RemoteLayerBackingStoreProperties) is destroyed.
We should run an explicit CATransaction for layer tree commits to ensure that
we always have a use-count added.
