/**
 * @brief Redefines the floor intensity of the Trace
 *
 * The amplitude of the trace is computed (maxValue - minValue)
 * Its fraction is calculated = amplitude * (percentage / 100)
 * The threshold value is computed as (minValue + fraction)
 *
 * When the values to be filtered are below that threshold they acquire that
 * threshold value.
 *
 * When the values to be filtered are above that threshold they remain
 * unchanged.
 *
 * This effectively re-floors the values to threshold.
