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

 461          * offsets[1].  Note that offsets[0] will generally
 462          * be 0 (but this is not required).
 463          *
 464          * To accommodate tiled, compressed, etc formats, a
 465          * modifier can be specified.  The default value of zero
 466          * indicates "native" format as specified by the fourcc.
 467          * Vendor specific modifier token.  Note that even though
 468          * it looks like we have a modifier per-plane, we in fact
 469          * do not. The modifier for each plane must be identical.
 470          * Thus all combinations of different data layouts for
