Hello, this is patch is for gtk+-0.99.4. It implements the following functions: 'gdk_window_shape_remove': removes a GdkWindow's shape mask that was set before by gdk_window_shape_combine_mask. 'gtk_widget_shape_remove': removes a GtkWidget's shape mask that was set before by gtk_widget_shape_combine_mask. This functionality was requested by Tim Janik. I have sent this patch about 4 weeks ago, but it probably didn't patch cleanly and didn't go into gtk+. Bye bye Stefan Wille
