This function is used by several others which can test pathes for certain properties (eg. _cairo_path_fixed_is_box()), but expect a pointer to cairo_box_t, which is passed to _canonical_box() for filling. In some cases we dont need that at all and dont wanna have the burden of maintaining that return structure, so allow that to be skiped by just passing a null pointer.
