    * BarSlider is a trackbar control written in C# as a replacement of the trackbar

    * CodeProject: https://www.codeproject.com/Tips/1193311/Csharp-Slider-Trackbar-Control-using-Windows-Forms
    * Github: https://github.com/fabricelacharme/BarSlider
    * 
    * 20/11/17 - version 1.0.O.1
    * 
    * Fixed: erroneous vertical display in case of minimum <> 0 (negative or positive)
    * Modified: DrawBarSlider, OnMouseMove
    * 
    * Added: Ticks display transformations
    * - TickAdd: allow to add a fixed value to the graduations: 
    *       usage: transform K = °C + 273,15, or °F = 1,8°C + 32   K = (°F + 459,67) / 1,8
    * - TickDivide: allow to diveide by a fixed value the graduations 
    *       usage: divide by 1000 => display graduations in kilograms when in gram
    *       
    *       
    * 10/12/17 - version 1.0.0.2
    * 
    * Added ForeColor property to graduations text color
