// PannerNode is an AudioNode with one input and one output.
// It positions a sound in 3D space, with the exact effect dependent on the
// panning model.  It has a position and an orientation in 3D space which is
// relative to the position and orientation of the context's AudioListener.  A
// distance effect will attenuate the gain as the position moves away from the
// listener.  A cone effect will attenuate the gain as the orientation moves
// away from the listener.  All of these effects follow the OpenAL specification
// very closely.
