@brief A fader compliant to IEC 60-268-18

This type of fader has several segments with different slopes that map deflection linearly to dB values. The segments are defined as in the following table:

@code Deflection | Volume

[ 100 %, 75 % ] | [ 0 dB, -9 dB ] [ 75 %, 50 % ] | [ -9 dB, -20 dB ] [ 50 %, 30 % ] | [ -20 dB, -30 dB ] [ 30 %, 15 % ] | [ -30 dB, -40 dB ] [ 15 %, 7.5 % ] | [ -40 dB, -50 dB ] [ 7.5 %, 2.5 % ] | [ -50 dB, -60 dB ] [ 2.5 %, 0 % ] | [ -60 dB, -inf dB ] @endcode
