-/* Multi-step advance functions (jump-ahead, jump-back)

- * The method used here is based on Brown, "Random Number Generation
- * with Arbitrary Stride,", Transactions of the American Nuclear
- * Society (Nov. 1994).  The algorithm is very similar to fast
- * exponentiation.
- *
- * Even though delta is an unsigned integer, we can pass a
- * signed integer to go backwards, it just goes "the long way round".
