	* X11ThreadQueue.cs (EnqueueUnlocked): add the switch motionnotify
	compression/NeedDispatchIdle assignment found in X11Hwnd here.
	(RemovePaintUnlocked): nuke
	(AddPaintUnlocked): nuke
	(AddConfigureUnlocked): rename to AddConfigure.

	Add some debug stuff to HwndEventQueue so we can see the stack
	trace of where the hwnd was added to the queue, in case we somehow
	try to add it multiple times.

	* X11Hwnd.cs (AddExpose): there's no need for this to have locks
	around it - it should only ever be called from operations on the
	hwnd's thread (from ScrollWindow, from GetMessage, from
	Invalidate).
	(AddConfigureNotify): same goes here.
	(HandleConfigureNotify): remove configure_lock reference.
	(EnqueueEvent): nuke this.
	(PaintEventStart): remove locking.
	(ScrollWindow): remove locking.

	also, remove all references to
	AddPaintUnlocked/RemovePaintUnlocked/AddConfigureUnlocked.  since
	we don't need to lock around them, there's not need.

	* X11Display.cs (XEventThread) switch from hwnd.EnqueueEvent to
	hwnd.Queue.Enqueue.
