    The main feature of this interface is accurate presentation timing feedback
    to ensure smooth video playback while maintaining audio/video
    synchronization. Some features use the concept of a presentation clock,
    which is defined in the presentation.clock_id event.

    A content update for a :class:`~pywayland.protocol.wayland.WlSurface` is
    submitted by a :func:`WlSurface.commit()
    <pywayland.protocol.wayland.WlSurface.commit>` request. Request 'feedback'
    associates with the :func:`WlSurface.commit()
    <pywayland.protocol.wayland.WlSurface.commit>` and provides feedback on the
    content update, particularly the final realized presentation time.



    When the final realized presentation time is available, e.g. after a
    framebuffer flip completes, the requested presentation_feedback.presented
    events are sent. The final presentation time can differ from the
    compositor's predicted display update time and the update's target time,
    especially when the compositor misses its target vertical blanking period.

        """Clock id for timestamps

        This event tells the client in which clock domain the compositor
        interprets the timestamps used by the presentation extension. This
        clock is called the presentation clock.

        The compositor sends this event when the client binds to the
        presentation interface. The presentation clock does not change during
        the lifetime of the client connection.

        The clock identifier is platform dependent. On Linux/glibc, the
        identifier value is one of the clockid_t values accepted by
        clock_gettime(). clock_gettime() is defined by POSIX.1-2001.

        Timestamps in this clock domain are expressed as tv_sec_hi, tv_sec_lo,
        tv_nsec triples, each component being an unsigned 32-bit value. Whole
        seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi
        and tv_sec_lo, and the additional fractional part in tv_nsec as
        nanoseconds. Hence, for valid timestamps tv_nsec must be in [0,
        999999999].

        Note that clock_id applies only to the presentation clock, and implies
        nothing about e.g. the timestamps used in the Wayland core protocol
        input events.

        Compositors should prefer a clock which does not jump and is not slewed
        e.g. by NTP. The absolute value of the clock is irrelevant. Precision
        of one millisecond or better is recommended. Clients must be able to
        query the current clock value directly, not by asking the compositor.
