    * 8 bit 2x2 subsampled colour difference samples.

    * offsets[1].  Note that offsets[0] will generally
    * be 0 (but this is not required).
    *
    * To accommodate tiled, compressed, etc formats, a per-plane
    * modifier can be specified.  The default value of zero
    * indicates "native" format as specified by the fourcc.
    * Vendor specific modifier token.  This allows, for example,
    * different tiling/swizzling pattern on different planes.
