	* DispatcherTimer.cs: Add new class.

	* Dispatcher.cs (ExitAllframes): Implement. 
	(everywhere): Add support for hooks.

	* DispatcherHooks: Implement
	
	* DispatcherOperation.cs: Store result. 

	* Dispatcher.cs: 
	Check frame.Continue for early termination.

	PokableQueue: new class used so we can move DispatcherOperation
	tasks from one thread to another.

	* Dispatcher.cs: Implement reprioritization.

	We now take locks instead of using a separate async queue, as
	things like DispatcherOperation.Priority (reprioritization) can be
	called from a separate thread without crashing.

	* Dispatcher.cs: Start with the Async methods.

2007-01-20  Miguel de Icaza  <miguel@novell.com>

	* Dispatcher.cs: Move all tasks, not only the first one from the
	async queue into the proper priority queues.

	Eliminate the `Task' class, it is mostly redundant, instead move
	all the data into DispatcherOperation.
	
	* DispatcherOperation.cs, DispatcherOperationStatus.cs: Add new
	files. 

	* Dispatcher.cs: Make our class `Task' internal, so we can pass
	that to DispatcherOperation.

	* Dispatcher.cs: Queue will now queue
	locally (if same thread) or post to the dispatcher queue if
	invoked from a different thread.

	* Dispatcher.cs: Initially I thought this
	was a stroke of genius.   Looking at the actual results, it does
	not seem as brilliant as I had hoped.
