/** \class SkRandom

 Utility class that implements pseudo random 32bit numbers using Marsaglia's
 multiply-with-carry "mother of all" algorithm. Unlike rand(), this class holds
 its own state, so that multiple instances can be used with no side-effects.

 Has a large period and all bits are well-randomized.
