9** NOTE: these values are not "magic" constants, but
10** are generated using the Threefish block function.
11** They are pre-computed here only for speed; i.e., to
12** avoid the need for a Threefish call during Init().
13**
14** The IV for any fixed hash length may be pre-computed.
15** Only the most common values are included here.
