Under the non-zero-winding rule, a path made up of two intersecting 
rectangles of opposite winding is a different shape than if the rectangles 
had the same winding.

Opposite winding would produce an xor, while same winding produces a union.

I think we want to allow rectangles to be added to the current path and 
represented compactly. Otherwise I'm not sure if this is going to be used.
