Fix bug of _find_shape_in_pos(). It can not find a correct shape for a specified point. Since it call _shape_pos_is_in_cairo() directly, cairo_new_path() is not called to clear path after each calling for a shape. So, old path would interference later testing. It should call _shape_pos_is_in() instead of _shape_pos_is_in_cairo().
