PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change. PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts. Double definitions will be removed in the (next) future.
