		* input channel and generates appropriate cancellations for all other windows that are
		* receiving these pointers.
		*
		* This API is intended to be used in conjunction with spy windows. When a spy window pilfers
		* pointers, the foreground windows and all other spy windows that are receiving any of the
		* pointers that are currently being dispatched to the pilfering window will have those pointers
		* canceled. Only the pilfering window will continue to receive events for the affected pointers
		* until the pointer is lifted.
		*
		* This method should be used with caution as unexpected pilfering can break fundamental user
		* interactions.
