	 * In case of planar formats, this ioctl allows up to 4

	 * buffer objects with offets and pitches per plane.

	 * The pitch and offset order is dictated by the fourcc,

	 * e.g. NV12 (http://fourcc.org/yuv.php#NV12) is described as:

	 *

	 *   YUV 4:2:0 image with a plane of 8 bit Y samples

	 *   followed by an interleaved U/V plane containing

	 *   8 bit 2x2 subsampled colour difference samples.

	 *

	 * So it would consist of Y as offset[0] and UV as

	 * offeset[1].  Note that offset[0] will generally

	 * be 0.
