        * gtk/gtkimage.c (gtk_image_expose): Optimize exposes of
        partial insensitive images.

2002-01-24  Havoc Pennington  <hp@redhat.com>

        * gtk/gtkimage.c (gtk_image_expose): create insensitive version of
        the image regardless of storage type, #63305

        * demos/gtk-demo/images.c: add toggle button to demonstrate that
        GtkImage makes its contents insensitive
