void GetStateAbsolute (GetStateAbsoluteCompleter::Sync & completer)Note: the device is calibrated at the factory to find a normalized brightness scale value that
corresponds to a set maximum brightness in nits. GetStateAbsolute() will return an error if
the normalized brightness scale is not set to the calibrated value, as there is no universal
way to map other scale values to absolute brightness.

void SetStateAbsolute (SetStateAbsoluteRequestView request, SetStateAbsoluteCompleter::Sync & completer)Note: this changes the normalized brightness scale back to the calibrated value in order to set
the absolute brightness.
