[Query] Seed the random number generator?

Neither Javascript's Math.random function nor the randomInteger function available for API scripts allows setting a seed. If you need to have the ability, there are a couple nice suggestions for how to implement it in JavaScript on StackOverflow. I particularly like the solution from Remco Kranenburg:

Math.seed = function(s) {
    return function() {
        s = Math.sin(s) * 10000; return s - Math.floor(s);
    };
};

Plus with an updated random number generator on the horizon, even if the answer is no today, it might change.

Not sure what you're talking about "on the horizon"?
