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

-     *    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

-     *    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.

-     *            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.
