Not interested in this at this time. Left for future
The change has floating point values between -1.0 and 1.0 to represent volume
changes between -100% to 100%.
A positive value (respectively negative), will increase (respectively decrease) the volume
by the percentage of the "remaining range" towards the maximum (respectively
minimum) value, i.e. difference between the current volume and the maximum
(respectively minimum) volume.
For example, when the volume range is [0-100] and we want to adjust by +50%:
If the current volume is 25, the increment will be:
"(100-25)*50%=75*0.5=38" (once rounded) so the new volume will be 63.
Another adjustment by +50% will be "(100-63)*0.5=19" to a volume of 82.
If we want instead to adjust by -50%, the decrement would be "(25-0)*0.5=13" to a
volume of 12, and another adjustment by -50% would be "(12-0)*0.5=6" to a volume of 6.
