    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.

        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 POSIX platforms, 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.

        The associated content update was displayed to the user at the
        indicated time (tv_sec_hi/lo, tv_nsec). For the interpretation of the
        timestamp, see presentation.clock_id event.

        The timestamp corresponds to the time when the content update turned
        into light the first time on the surface's main output. Compositors may
        approximate this from the framebuffer flip completion events from the
        system, and the latency of the physical display path if known.

        This event is preceded by all related sync_output events telling which
        output's refresh cycle the feedback corresponds to, i.e. the main
        output for the surface. Compositors are recommended to choose the
        output containing the largest part of the
        :class:`~pywayland.protocol.wayland.WlSurface`, or keeping the output
        they previously chose. Having a stable presentation output association
        helps clients predict future output refreshes (vblank).

        The 'refresh' argument gives the compositor's prediction of how many
        nanoseconds after tv_sec, tv_nsec the very next output refresh may
        occur. This is to further aid clients in predicting future refreshes,
        i.e., estimating the timestamps targeting the next few vblanks. If such
        prediction cannot usefully be done, the argument is zero.

        For version 2 and later, if the output does not have a constant refresh
        rate, explicit video mode switches excluded, then the refresh argument
        must be either an appropriate rate picked by the compositor (e.g.
        fastest rate), or 0 if no such rate exists. For version 1, if the
        output does not have a constant refresh rate, the refresh argument must
        be zero.

        The 64-bit value combined from seq_hi and seq_lo is the value of the
        output's vertical retrace counter when the content update was first
        scanned out to the display. This value must be compatible with the
        definition of MSC in GLX_OML_sync_control specification. Note, that if
        the display path has a non-zero latency, the time instant specified by
        this counter may differ from the timestamp's.

        If the output does not have a concept of vertical retrace or a refresh
        cycle, or the output device is self-refreshing without a way to query
        the refresh count, then the arguments seq_hi and seq_lo must be zero.
