Fix mis-behavior of translate_path_data() on arc. - Arc in a path in svg2code_ex is not showed. - translate_path_data() in svg2code.py was modified for calling binary version new method for path shape. - rdman_shape_path_new_from_binary() - Code to translate path data does not handle arc in a right way. - Copy calc_center_and_x_aix() from shape_path.c to svg2code.py and change name _calc_ellipse_of_arc() - _calc_ellipse_of_arc() handle arc data for translate_path_data()
