        * gdk/x11/gdkdrawable-x11.c (draw_with_pixmaps): Fix a
        problem where were the offset into the image was passed
        into convert_to_format() wrong.

        * gdk/x11/gdkdrawable-x11.c (gdk_x11_draw_pixbuf): Call
        gdk_x11_drawable_update_picture_clip () before using
        the picture; allow update_picture_clip() to take a NULL gc
        to mean no clipping.
