 |

 | 
| -     * INTENDED USE:
 | 
| -     *
 | 
| -     * The transform hint can be used by a producer, for instance the GLES
 | 
| -     * driver, to pre-rotate the rendering such that the final transformation
 | 
| -     * in the composer is identity. This can be very useful when used in
 | 
| -     * conjunction with the h/w composer HAL, in situations where it
 | 
| -     * cannot handle arbitrary rotations.
 | 
| -     *
 | 
| -     * 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:
 | 
| -     *
 | 
| -     *        int hintTransform, inverseTransform;
 | 
| -     *        query(..., NATIVE_WINDOW_TRANSFORM_HINT, &hintTransform);

| -     *        inverseTransform = hintTransform;
 |

 | 
| -     *            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
 |
