Detailed Description

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.
