* transformation that will most-likely be applied to buffers. This is only

*
* 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;
* if (hintTransform & HAL_TRANSFORM_ROT_90)
* 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.
