Well, almost. It turns out that operator+= can only skip one tile at a time, 
making the effect still weird. After rewriting that as well, it finally seems 
to work completely (unfortunately, slower than the old one, so it seems a bit 
like a waste).

Would you mind if I committed this? (together with the adapted operator+=)
