	The scale event describes an available scale for the output.

	The event is sent when binding to the output object and there
	will always be one scale, the current scale. The event is sent
	again if an output changes scale, for the scale that is now
	current. In other words, the current scale is always the last
	scale that was received with the current flag set.

	The device specific scale factor is not expected the change during
