Marcin Gasperowicz 3039c36836 AudioApplet: Make the slider exponential for finer volume control ...

The volume slider was linear, which is not ideal for an audio volume 
control. Perceived volume would not change much within 30-100% range
and would change in leaps within 0-30% range where the resolution is
not sufficient for fine grained control.

The simplest solution is to bring the value into 0.0-1.0 range and 
square it to obtain an exponential curve. This is a decent 
approximation of the logarithmic taper used in audio potentiometers.
