+// seedrandom.js version 2.0.
+// Author: David Bau 4/2/2011
+//
+// Defines a method Math.seedrandom() that, when called, substitutes
+// an explicitly seeded RC4-based algorithm for Math.random(). Also
+// supports automatic seeding from local or network sources of entropy.
+//
+// Usage:
+//
+// <script src=http://davidbau.com/encode/seedrandom-min.js></script>
+//
+// Math.seedrandom('yipee'); Sets Math.random to a function that is
+// initialized using the given explicit seed.
+//
+// Math.seedrandom(); Sets Math.random to a function that is
+// seeded using the current time, dom state,
+// and other accumulated local entropy.
+// The generated seed string is returned.
+//
+// Math.seedrandom('yowza', true);
+// Seeds using the given explicit seed mixed
+// together with accumulated entropy.
+//
+// <script src="http://bit.ly/srandom-512"></script>
+// Seeds using physical random bits downloaded
+// from random.org.
+//
+// <script src="https://jsonlib.appspot.com/urandom?callback=Math.seedrandom">
+// </script> Seeds using urandom bits from call.jsonlib.com,
+// which is faster than random.org.
+//
+// Examples:
+//
+// Math.seedrandom("hello"); // Use "hello" as the seed.
+// document.write(Math.random()); // Always 0.5463663768140734
+// document.write(Math.random()); // Always 0.43973793770592234
+// var rng1 = Math.random; // Remember the current prng.
+//
+// var autoseed = Math.seedrandom(); // New prng with an automatic seed.
+// document.write(Math.random()); // Pretty much unpredictable.
+//
+// Math.random = rng1; // Continue "hello" prng sequence.
+// document.write(Math.random()); // Always 0.554769432473455
+//
+// Math.seedrandom(autoseed); // Restart at the previous seed.
+// document.write(Math.random()); // Repeat the 'unpredictable' value.
+//
+// Notes:
+//
+// Each time seedrandom('arg') is called, entropy from the passed seed
+// is accumulated in a pool to help generate future seeds for the
+// zero-argument form of Math.seedrandom, so entropy can be injected over
+// time by calling seedrandom with explicit data repeatedly.
+//
+// On speed - This javascript implementation of Math.random() is about
+// 3-10x slower than the built-in Math.random() because it is not native
+// code, but this is typically fast enough anyway. Seeding is more expensive,
+// especially if you use auto-seeding. Some details (timings on Chrome 4):
+//
+// Our Math.random() - avg less than 0.002 milliseconds per call
+// seedrandom('explicit') - avg less than 0.5 milliseconds per call
+// seedrandom('explicit', true) - avg less than 2 milliseconds per call
+// seedrandom() - avg about 38 milliseconds per call
