Gets the gtk.cell_renderer.CellRenderer which is expected to be focusable for which renderer is, or may be a sibling.
This is handy for gtk.cell_area.CellArea subclasses when handling events, after determining the renderer at the event location it can then chose to activate the focus cell for which the event cell may have been a sibling.
