+     *
+     * 1. After a configuration change, before dequeuing a buffer, the buffer producer queries the
+     *    function for the transform hint.
+     *
+     * 2. The desired buffer width and height is rotated by the transform hint.
+     *
+     * 3. The producer dequeues a buffer of the new pre-rotated size.
+     *
+     * 4. The producer renders to the buffer such that the image is already transformed, that is
+     *    applying the transform hint to the rendering.
+     *
+     * 5. The producer applies the inverse transform hint to the buffer it just rendered.
+     *
+     * 6. The producer queues the pre-transformed buffer with the buffer transform.
+     *
+     * 7. The composer combines the buffer transform with the display transform.  If the buffer
+     *    transform happens to cancel out the display transform then no rotation is needed and there
+     *    will be no performance penalties.
+     *
+     * Note, when using ANativeWindow APIs in conjunction with a NativeActivity Surface or
+     * SurfaceView Surface, the buffer producer will already have access to the transform hint and
+     * no additional work is needed.

+/**
+ * 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>
