| /** |
| * Controls the power state of the display. |
| * |
| * Handles the proximity sensor, light sensor, and animations between states |
| * including the screen off animation. |
| * |
| * This component acts independently of the rest of the power manager service. |
| * In particular, it does not share any state and it only communicates |
| * via asynchronous callbacks to inform the power manager that something has |
| * changed. |
| * |
| * Everything this class does internally is serialized on its handler although |
| * it may be accessed by other threads from the outside. |
| * |
| * Note that the power manager service guarantees that it will hold a suspend |
| * blocker as long as the display is not ready. So most of the work done here |
| * does not need to worry about holding a suspend blocker unless it happens |
| * independently of the display ready signal. |
| * |
| * For debugging, you can make the color fade and brightness animations run |
| * slower by changing the "animator duration scale" option in Development Settings. |
