Not applicable to all display types. * - WSDISPLAYIO_PARAM_BACKLIGHT should be an on/off switch for screensavers, * it should turn the display dark / turn the backlight off without changing * the brightness value so screensavers and such can just flip the switch * without caring about actual brightness settings * - WSDISPLAYIO_PARAM_BRIGHTNESS should set display / backlight brightness */
