//       Class : NativeWindowHandle
// Description : This subclass of WindowHandle exists to allow simple
//               creation of a WindowHandle of the appropriate type to
//               the current OS.
//
//               This class exists for name scoping only.  Don't use
//               the constructor directly; use one of the make_*
//               methods.
