Gtk.CellArea.prototype.request_renderer

function request_renderer(renderer:Gtk.CellRenderer, orientation:Gtk.Orientation, widget:Gtk.Widget, for_size:Number):void {
    // Gjs wrapper for gtk_cell_area_request_renderer()
}

This is a convenience function for Gtk.CellArea implementations to request size for cell renderers. It's important to use this function to request size and then use Gtk.CellArea.prototype.inner_cell_area at render and event time since this function will add padding around the cell for focus painting.
