368 * The pitch and offset order is dictated by the fourcc,
369 * e.g. NV12 (http://fourcc.org/yuv.php#NV12) is described as:
371 * YUV 4:2:0 image with a plane of 8 bit Y samples
372 * followed by an interleaved U/V plane containing
373 * 8 bit 2x2 subsampled colour difference samples.
375 * So it would consist of Y as offsets[0] and UV as
376 * offsets[1]. Note that offsets[0] will generally
377 * be 0 (but this is not required).
379 * To accommodate tiled, compressed, etc formats, a per-plane
380 * modifier can be specified. The default value of zero
381 * indicates "native" format as specified by the fourcc.
382 * Vendor specific modifier token. This allows, for example,
383 * different tiling/swizzling pattern on different planes.
