Detailed Description

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)
