// WCPTRegion stands for WorldCanvas Polygon Tool Region
// </etymology>
// <synopsis>
// This class finalises the functionality in WCRectTool to
// implement event-based drawing of polygonal regions on a
// WorldCanvas. casacore::Double clicking inside the constructed polygon
// emits the region, whilst pressing Escape cancels the region.
// </synopsis>
// <example>
// </example>
// <motivation>
// Polygonal regions are the most common regions, and constructing
// them visually can be very efficient.
