Well, in case memory outside the screen is accessed, it will crash. I
just wasn't sure if there's something in the screen vtable preventing
that, or maybe blit and draw_sprite never draw outside, even with
clipping disabled.. anyway, I'll search the archives as suggested by
Eric, I guess we may need some sort of solution, enven if it's just a
warning in the docs.
