Window.mergeChildShapes

Merges the shape masks for any child windows into the shape mask for @window. i.e. the union of all masks for @window and its children will become the new mask for @window. See gdk_window_shape_combine_region().

This function is distinct from gdk_window_set_child_shapes() because it includes @window’s shape mask in the set of shapes to be merged.
