+ *	The 'GSRunLoopWatcher' class was written to permit the (relatively)
+ *	easy addition of new events to be watched for in the runloop.
+ *
+ *	To add a new type of event, the 'RunLoopEventType' enumeration must be
+ *	extended, and the methods must be modified to handle the new type.
+ *
+ *	The internal variables if the GSRunLoopWatcher are used as follows -
+ *
+ *	The '_date' variable contains a date after which the event is useless
+ *	and the watcher can be removed from the runloop.
+ *
+ *	If '_invalidated' is set, the watcher should be disabled and should
+ *	be removed from the runloop when next encountered.
+ *
+ *	The 'data' variable is used to identify the  resource/event that the
+ *	watcher is interested in.
+ *
+ *	The 'receiver' is the object which should be told when the event
+ *	occurs.  This object is retained so that we know it will continue
+ *	to exist and can handle a callback.
+ *
+ *	The 'type' variable indentifies the type of event watched for.
+ *	NSRunLoops [-acceptInputForMode: beforeDate: ] method MUST contain
+ *	code to watch for events of each type.
+ *
+ *	To set this variable, the method adding the GSRunLoopWatcher to the
+ *	runloop must ask the 'receiver' (or its delegate) to supply a date
+ *	using the '[-limitDateForMode: ]' message.
+ *
+ *	NB.  This class is private to NSRunLoop and must not be subclassed.
