// <synopsis>
// The WCComplement class is a specialization of class
// <linkto class=WCCompound>WCCompound</linkto>.
// It makes it possible to take the complement of the given region
// (which can be a simple WCBox, but also a complex compound region).
// Note that only world coordinate regions can be used in a compound,
// thus an LCSlicer object is not allowed in an intersection.
// <p>
// Note that a region consists of all its masked-on pixels inside the
// bounding box of the region. Thus the complement consists of all
// pixels outside the bounding box and all masked-off pixels inside
// the bounding box. So the complement of the complement of a region
// is the region itself.
