Chain operators onto an array: [waveScope].kaleid(6).hue(0.1). Each operator processes the image drawn so far in that layer.

Numeric arguments may be numbers or ({ audio, time }) => value. Operators run in written order. For wet/dry mix, blend mode, or bypass, create a new ShaderChain() and append it with .fx(chain). The shader's shift() is colorShift() on arrays; native array shift() still removes the first entry.
