        * app/gui/about-dialog.c
        * app/widgets/gimpimagefilepreview.c
        * app/widgets/gimptoolbox-color-area.c: use gdk_draw_pixbuf with
        GTK+ 2.2 or higher instead of gdk_pixbuf_render_to_drawable.
        That function will be deprecated in GTK+ 2.4. We should remove the
        fallback at some point when we start depending on GTK+ 2.2 for other
        stuff.
