/**
 * KisSpinBoxSplineUnitConverter is a class that converts points
 *  from ranges(0, 1) to ranges (min, max).
 * In case of reverted ranges (min > max),
 *  smaller values from range (0, 1) correspond
 *  to bigger values from range (min, max)
 *  and the other way around.
 * Example:
 *  3 from (0, 10) is 0.3 from (0, 1)
 *  3 from (10, 0) is 0.7 from (0, 1)
