      <p>Hello Javier</p>

      <p>Even can answer better, but I suspect that the code applies the

        convention saying that W > E means that the envelope is

        crossing the anti-meridian. There is a picture there:<br>

      <p>With such convention, the tests for contains and intersections

        become more complicated. There is a picture for contains, but

        the situation is similar for intersection:</p>
