Hi Paul, But how should one render something that at most zero sized? It's a invalid size, at best I think one should render nothing for things that are zero sized.
Personally I think one should just reject invalid data like this, best done prior to rendering to avoid valid data and applications being burdened by filtering invalid data at render time.
