| /** |
| * This class handles the rotation animation when the device is rotated. |
| * |
| * <p> |
| * The screen rotation animation is composed of 4 different part: |
| * <ul> |
| * <li> The screenshot: <p> |
| * A screenshot of the whole screen prior the change of orientation is taken to hide the |
| * element resizing below. The screenshot is then animated to rotate and cross-fade to |
| * the new orientation with the content in the new orientation. |
| * |
| * <li> The windows on the display: <p>y |
| * Once the device is rotated, the screen and its content are in the new orientation. The |
| * animation first rotate the new content into the old orientation to then be able to |
| * animate to the new orientation |
| * |
| * <li> The Background color frame: <p> |
| * To have the animation seem more seamless, we add a color transitioning background behind the |
| * exiting and entering layouts. We compute the brightness of the start and end |
| * layouts and transition from the two brightness values as grayscale underneath the animation |
| * |
| * <li> The entering Blackframe: <p> |
| * The enter Blackframe is similar to the exit Blackframe but is only used when a custom |
| * rotation animation is used and matches the new content size instead of the screenshot. |
| * </ul> |
| * |
| * Each part has its own Surface which are then animated by {@link SurfaceAnimator}s. |
