public class GainMeterButton
extends BasicControlButton
implements GainMeter

The gain meter button for StandardControlPanel. This class draws the default gain meter button for StandardControls: A small speaker-shaped icon with "waves" emanating from the front.

A read X is drawn atop the speaker when the gain control is muted. As the gain increase, more "waves" are drawn. As the gain decreases, fewer "waves" are drawn.

GainMeterButton implements GainMeter in order to support these operations.
