    You now have to use a GdkDrawingContext

- * gdk_window_begin_paint_region:
- * @window: a #GdkWindow
- * @region: region you intend to draw to
- *
- * Indicates that you are beginning the process of redrawing @region.
- * A backing store (offscreen buffer) large enough to contain @region
- * will be created. The backing store will be initialized with the
- * background color or background surface for @window. Then, all
- * drawing operations performed on @window will be diverted to the
- * backing store.  When you call gdk_window_end_paint(), the backing
- * store will be copied to @window, making it visible onscreen. Only
- * the part of @window contained in @region will be modified; that is,
- * drawing operations are clipped to @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
- * gdk_window_end_paint(). If you draw to @window directly without
- * calling gdk_window_begin_paint_region(), the user may see flicker
- * as individual drawing operations are performed in sequence.  The
- * clipping and background-initializing features of
- * gdk_window_begin_paint_region() are conveniences for the
- * programmer, so you can avoid doing that work yourself.
- *
- * When using GTK+, the widget system automatically places calls to
- * gdk_window_begin_paint_region() and gdk_window_end_paint() around
- * emissions of the expose_event signal. That is, if you’re writing an
- * expose event handler, you can assume that the exposed area in
- * #GdkEventExpose has already been cleared to the window background,
- * is already set as the clip region, and already has a backing store.
- * Therefore in most cases, application code need not call
- * gdk_window_begin_paint_region(). (You can disable the automatic
- * calls around expose events on a widget-by-widget basis by calling
- * gtk_widget_set_double_buffered().)
- *
- * If you call this function multiple times before calling the
- * matching gdk_window_end_paint(), the backing stores are pushed onto
- * a stack. gdk_window_end_paint() copies the topmost backing store
- * onscreen, subtracts the topmost region from all other regions in
- * the stack, and pops the stack. All drawing operations affect only
- * the topmost backing store in the stack. One matching call to
- * gdk_window_end_paint() is required for each call to
- * gdk_window_begin_paint_region().
- *
- * Deprecated: 3.22: Use gdk_window_begin_draw_frame() instead
