XCBSurfacea/The XCB surface is used to render cairo graphics to X Window System
    windows and pixmaps using the XCB library.

    Creates a cairo surface that targets the given drawable (pixmap or window).

    .. note::

        This class works using objects and libraries in ``xcffib``.

    :param conn: The ``xcffib.Connection`` for an open XCB connection
    :param drawable:
        An XID corresponding to an XCB drawable (a pixmap or a window)
    :param visual: An ``xcffib.xproto.VISUALTYPE`` object.
    :param width: integer
    :param height: integer

        Informs cairo of the new size of the X Drawable underlying the surface.
        For a surface created for a Window (rather than a Pixmap), this
        function must be called each time the size of the window changes (for
        a subwindow, you are normally resizing the window yourself, but for a
        toplevel window, it is necessary to listen for
        :class:`xcffib.xproto.ConfigureNotifyEvent`'s).

        A Pixmap can never change size, so it is never necessary to call this
        function on a surface created for a Pixmap.
