-// Commit Flow: The commit flow defines the protocol for data exchange between
-//              the client and the server. The commit flow is characterized by
-//              the following messages.
-//
-//              1) The commit will always be started by the client. The server
-//                 may request a commit from the client by sending a
-//                 CompositorMessageToImpl of type SET_NEEDS_COMMIT. Note that
-//                 if the server needs to push any updates to the client, this
-//                 message will only be sent once, and the client must respond
-//                 with CompositorMessageToMain of type BEGIN_MAIN_FRAME to
-//                 start the commit.
-//                 The client can spontaneously initiate a commit when it needs
-//                 to request new data from the server by sending the
-//                 BEGIN_MAIN_FRAME message.
-//
-//              2) On receiving BEGIN_MAIN_FRAME message, the server can respond
-//                 with either CompositorMessageToImpl of type START_COMMIT, if
-//                 it needs to push an update to the client, or of type
-//                 BEGIN_MAIN_FRAME_ABORTED if the commit was aborted.
