/* This protocol's primary use is so widget/cocoa can talk back to us

   properly.

   ChildView owns the topmost MUIRootAccessible, and needs to take care of

   setting up that parent/child relationship.

   This protocol is thus used to make sure it knows it's talking to us, and not

   just some random |id|.
