+     *
+     * The transform hint can be used by a producer, for instance the GLES

+     * 1. Before dequeuing a buffer, the GL driver (or any other ANW client)
+     *    queries the ANW for NATIVE_WINDOW_TRANSFORM_HINT.
+     *
+     * 2. The GL driver overrides the width and height of the ANW to
+     *    account for NATIVE_WINDOW_TRANSFORM_HINT. This is done by querying
+     *    NATIVE_WINDOW_DEFAULT_{WIDTH | HEIGHT}, swapping the dimensions
+     *    according to NATIVE_WINDOW_TRANSFORM_HINT and calling
+     *    native_window_set_buffers_dimensions().
+     *
+     * 3. The GL driver dequeues a buffer of the new pre-rotated size.
+     *
+     * 4. The GL driver renders to the buffer such that the image is
+     *    already transformed, that is applying NATIVE_WINDOW_TRANSFORM_HINT
+     *    to the rendering.
+     *
+     * 5. The GL driver calls native_window_set_transform to apply
+     *    inverse transformation to the buffer it just rendered.
+     *    In order to do this, the GL driver needs
+     *    to calculate the inverse of NATIVE_WINDOW_TRANSFORM_HINT, this is
+     *    done easily:

+     *            inverseTransform ^= HAL_TRANSFORM_ROT_180;
+     *
+     *
+     * 6. The GL driver queues the pre-transformed buffer.
+     *
+     * 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.
