  28          Purpose:
  29            Calc intersection of rectangles
  30          Add. info:
  31            Rectangles are passed as pointers. These pointers need to be valid;
  32            a NULL pointer may not be passed. There is no check for NULL pointers
  33            implemented in order to avoid avoid performance penalty.
  34            There is a similar function available, GUI__IntersectRects(),
  35            which takes 3 parameters and
  36            has a return value. Note that this one should be preferred because
  37            it is considerably faster and the call requires one parameter less.
