 // Specialization of the output surface that adapts it to implement the

 // layer, instead of driven by the compositor internals - hence it holds two
 // 'client' pointers (|client_| in the OutputSurface baseclass and
 // GetDelegate()) which represent the consumers of the two roles in plays.
 // This class can be created only on the main thread, but then becomes pinned
 // to a fixed thread when BindToClient is called.
