intersectsEnvelopeCoords static method
Tests whether the envelope defined by p1-p2 and the envelope defined by q1-q2 intersect.
@param p1 one extremal point of the envelope P
@param p2 another extremal point of the envelope P
@param q1 one extremal point of the envelope Q
@param q2 another extremal point of the envelope Q
@return true
if Q intersects P
