Convert the BrightnessController to a log scale control. Currently, the BrightnessController's UI is a linear scale control on top of a linear backlight control, but humans perceive brightness on a roughly logarithmic scale. By moving to a non-linear control, we both give users more fine-grained control over the brightness of the display as well as a UI that works more intuitively.
