<!-- Array of light sensor lux values to define our levels for auto backlight brightness support.

The N entries of this array define N + 1 control points as follows:
|
|
(1-based arrays)
|
|
Point 1: (0, value[1]): lux <= 0
|
|
Point 2: (level[1], value[2]): 0 < lux <= level[1]
|
|
Point 3: (level[2], value[3]): level[2] < lux <= level[3]
|
|
...
|
|
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.
