+         Point 1:            (0, value[1]):             lux <= 0

+
+         The control points must be strictly increasing.  Each control point
+         corresponds to an entry in the brightness backlight values arrays.

+         then the brightness will be determined by value[2] (second element
+         of the brightness values array).
+

+         backlight values for LUX levels between these control points.
