// <synopsis>
// This class adds to its base MWCTool to provide a tool for drawing,
// reshaping and moving polygons on a WorldCanvas. While MWCPolyTool
// is not abstract, it performs no useful function. The programmer
// should derive from this class and override the functions doubleInside
// and doubleOutside at the very least. These are called when the user
// double-clicks a particular key or mouse button inside or outside an
// existing polygon respectively. It is up to the programmer to decide
// what these events mean, but it is recommended that an internal double-
// click correspond to the main action of the tool, eg. emitting the
