-     *
-     * 2. The GL driver overrides the width and height of the ANW to
-     *    account for NATIVE_WINDOW_TRANSFORM_HINT. This is done by querying

-     *
-     * 6. The GL driver queues the pre-transformed buffer.
-     *
-     * 7. The composer combines the buffer transform with the display
