    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.

It's a shame all of these x.reset() dweets don't work on iOS... :(
u/rodrigo.siqueira

...thanks for letting me know about this iOS limitation. So, I’ll stop using x.reset and go back to using c.width instead.

Should be noted reset is working fine in iOS 18.1

Dwitter could also monkey-patch 2d context to get x.reset() working
