-// Represents the output surface for a compositor. The compositor owns

-//   2. Passed to the compositor thread and bound to a client via BindToClient.
-//      From here on, it will only be used on the compositor thread.
-//   3. If the 3D context is lost, then the compositor will delete the output
-//      surface (on the compositor thread) and go back to step 1.
