Backlight settings, preliminary, but works

    void setBacklightBrightness(int brightness);

    void setAttentionLight(boolean on, int color);

    void setAutoBrightnessAdjustment(float adj);

    // custom backlight things

    int getLightSensorValue();

    int getRawLightSensorValue();

    int getLightSensorScreenBrightness();

    int getLightSensorButtonBrightness();

    int getLightSensorKeyboardBrightness();

}
