			// ##### touchMedia
			// Sometimes you want to display distinct media for touch devices.
			// For these cases, the stimulus object supports the `touchMedia` parameter
			// that accepts an alternative media object that will be displayed on touch devices instead of the regular one.
			// If a `touchMedia` parameter is not defined the regular media will be used instead.
