Abstraction for hexagonal constant-intensity panning

For speakers that are configured in a circle or in the vertices of a regular polygon, you can give a sense of localization of a sound by calculating the radial angle of the sound's desired virtual location relative to the center of the listening space, and then panning the sound between the speakers that are closest to that virtual location. In other words, for any virtual location that you want to imply, you need to calculate which speakers are closest to that location, and then pan the sound between those speakers.
