   2  * Pre-computed Skein IVs
   3  *
   4  * NOTE: these values are not "magic" constants, but
   5  * are generated using the Threefish block function.
   6  * They are pre-computed here only for speed; i.e., to
   7  * avoid the need for a Threefish call during Init().
   8  *
   9  * The IV for any fixed hash length may be pre-computed.
  10  * Only the most common values are included here.
