VLC volume control redesign: find the right formula
completed by: Jeppe Hallgren
mentors: Jean-Baptiste Kempf
Indepentently to the Volume widget redesign, we have to find the right binding between the volume widget abscissa and the volume.
Find the function, where x goes from 0 to 100 (widget abscissa) and the volume percentage between 0 and 400%
f(0) = 0
f(100) = 400
Mapping to ]-Y dB; 6dB[ might be a good idea. Y to be defined.
