         The N entries of this array define N + 1 control points as follows:
         (1-based arrays)

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

         Point N+1: (level[N], value[N+1]):  level[N] < lux

         The control points must be strictly increasing.  Each control point
         corresponds to an entry in the brightness backlight values arrays.
         For example, if lux == level[1] (first element of the levels array)
         then the brightness will be determined by value[2] (second element
         of the brightness values array).

         Spline interpolation is used to determine the auto-brightness
         backlight values for lux levels between these control points.
