   * 
   * If @a window is a top level Gdk::Window, backed by a native window
   * implementation, a backing store (offscreen buffer) large enough to
   * contain @a region will be created. The backing store will be initialized
   * with the background color or background surface for @a window. Then, all
   * drawing operations performed on @a window will be diverted to the
   * backing store. When you call gdk_window_end_frame(), the contents of
   * the backing store will be copied to @a window, making it visible
   * on screen. Only the part of @a window contained in @a region will be
   * modified; that is, drawing operations are clipped to @a region.
   * 
   * The net result of all this is to remove flicker, because the user
   * sees the finished product appear all at once when you call
   * end_draw_frame(). If you draw to @a window directly without
   * calling begin_draw_frame(), the user may see flicker
   * as individual drawing operations are performed in sequence.
   * 
   * When using GTK+, the widget system automatically places calls to
   * begin_draw_frame() and end_draw_frame() around
   * emissions of the `GtkWidget::draw` signal. That is, if you’re
   * drawing the contents of the widget yourself, you can assume that the
   * widget has a cleared background, is already set as the clip region,
   * and already has a backing store. Therefore in most cases, application
   * code in GTK does not need to call begin_draw_frame()
   * explicitly.
   * 
   * @newin{3,22}
   * 
   * @param region A Cairo region.
   * @return A Gdk::DrawingContext context that should be
   * used to draw the contents of the window; the returned context is owned
