Specify a clip rect for ChildSceneLayers.
Specify a clip rect for ChildSceneLayers.

When linking in a scene, it's a good idea to specify its clip rectangle
to ensure that its content does not draw or capture input from its
surrounding space.

A future version of the Mozart view manager may automatically wrap a
view's scene with a clip rectangle to avoid composition gotchas like this
but it currently doesn't.  So the net effect is that if you embed a view
without specifying a clip, it can draw or capture input from anywhere
within its container.
