    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

@yonatan Thanks! I'm enjoying getting into this, and a Phong shader seemed like a good goal.

you can do M.sqrt() with ES6 power operator as **.5 should yield a net gain of 2 chars

Oh right! I haven't gotten used to it yet since I'm on Fx51, which doesn't seem to support ** yet. Thanks!
