This patch changes the audio mixer faders to use a non-linear algorithm for volume control. The intention is to make Godot's audio faders be more like those found in professional audio equipment and programs. It is an exponential equation which intends to counter-act the logarithmic nature of human hearing. The effect of this is a more usable audio mixer with more emphasis on the values that make the most difference to the mix. It also changes the audio level notch widget to be less static and thus supports changing the scaling factor of the audio faders.
