        * image-overlay.[ch]: Rewrite most of the information overlay code to
        be more flexible and easily extended.
        * image.[ch], typedefs.h: Remove image_new_func, and replace it with
        image_state_func callback which is much more informative.
        * img-view.c, layout.c, layout_image.c: Updates for new image overlay
        function names.
