  39            Calc intersection of rectangles
  40          Return value:
  41            1 if they do intersect,
  42            0 if there is no intersection
  43          Add. info:
  44            Rectangles are passed as pointers. These pointers need to be valid;
  45            a NULL pointer may not be passed. There is no check for NULL pointers
  46            implemented in order to avoid avoid performance penalty.
