Return destination from AudioNode::connect()

[chrislo]

The following issue was raised by the W3C TAG as part of their review of the Web Audio API

Why doesn't AudioNode::connect() return the passed AudioNode destination? It would enable a much terser chained style in some cases. Janessa Det provides the example of:

  oneShotSound.connect(lowpass);
  lowpass.connect(panner);
  panner.connect(gainNode2);
  gainNode2.connect(compressor);
  compressor.connect(destination);

becoming:

  oneShotSound
      .connect(lowpass)
      .connect(panner)
      .connect(gainNode2)
      .connect(compressor)
      .connect(destination);
