   * @page page_vsync_feedback_unstable_v1 The vsync_feedback_unstable_v1 protocol
   * Protocol for providing vertical synchronization timing
   *
   * @section page_desc_vsync_feedback_unstable_v1 Description
   *
   * This protocol specifies a set of interfaces used to inform the client about
   * vertical synchronization timing in a precise way and without unnecessary
   * overhead.
   *
   * Warning! The protocol described in this file is experimental and backward
   * incompatible changes may be made. Backward compatible changes may be added
   * together with the corresponding interface version bump. Backward
   * incompatible changes are done by bumping the version number in the protocol
   * and interface names and resetting the interface version. Once the protocol
   * is to be declared stable, the version number in the protocol is removed and
   * the interface version number is reset.
