        This asks for creation of a
        :class:`~pywayland.protocol.wayland.WlBuffer` from the added dmabuf
        buffers. The :class:`~pywayland.protocol.wayland.WlBuffer` is not
        created immediately but returned via the 'created' event if the dmabuf
        sharing succeeds. The sharing may fail at runtime for reasons a client
        cannot predict, in which case the 'failed' event is triggered.

        The 'format' argument is a DRM_FORMAT code, as defined by the libdrm's
        drm_fourcc.h. The Linux kernel's DRM sub-system is the authoritative
        source on how the format codes should work.

        The 'flags' is a bitfield of the flags defined in enum "flags".
        'y_invert' means the that the image needs to be y-flipped.

        Flag 'interlaced' means that the frame in the buffer is not progressive
        as usual, but interlaced. An interlaced buffer as supported here must
        always contain both top and bottom fields. The top field always begins
        on the first pixel row. The temporal ordering between the two fields is
        top field first, unless 'bottom_first' is specified. It is undefined
        whether 'bottom_first' is ignored if 'interlaced' is not set.

        This protocol does not convey any information about field rate,
        duration, or timing, other than the relative ordering between the two
        fields in one buffer. A compositor may have to estimate the intended
        field rate from the incoming buffer rate. It is undefined whether the
        time of receiving :func:`WlSurface.commit()
        <pywayland.protocol.wayland.WlSurface.commit>` with a new buffer
        attached, applying the :class:`~pywayland.protocol.wayland.WlSurface`
        state, :func:`WlSurface.frame()
        <pywayland.protocol.wayland.WlSurface.frame>` callback trigger,
        presentation, or any other point in the compositor cycle is used to
        measure the frame or field times. There is no support for detecting
        missed or late frames/fields/buffers either, and there is no support
        whatsoever for cooperating with interlaced compositor output.

        The composited image quality resulting from the use of interlaced
        buffers is explicitly undefined. A compositor may use elaborate
        hardware features or software to deinterlace and create progressive
        output frames from a sequence of interlaced input buffers, or it may
        produce substandard image quality. However, compositors that cannot
        guarantee reasonable image quality in all cases are recommended to just
        reject all interlaced buffers.

        Any argument errors, including non-positive width or height, mismatch
        between the number of planes and the format, bad format, bad offset or
        stride, may be indicated by fatal protocol errors: INCOMPLETE,
        INVALID_FORMAT, INVALID_DIMENSIONS, OUT_OF_BOUNDS.

        Dmabuf import errors in the server that are not obvious client bugs are
        returned via the 'failed' event as non-fatal. This allows attempting
        dmabuf sharing and falling back in the client if it fails.

        This request can be sent only once in the object's lifetime, after
        which the only legal request is destroy. This object should be
        destroyed after issuing a 'create' request. Attempting to use this
        object after issuing 'create' raises ALREADY_USED protocol error.

        It is not mandatory to issue 'create'. If a client wants to cancel the
        buffer creation, it can just destroy this object.

        invalid :class:`~pywayland.protocol.wayland.WlBuffer` as an argument in
