C# NumericUpDown MouseWheel event

NumericUpDown MouseWheel

class MyNumericUpDown : NumericUpDown
{
    protected override void OnMouseWheel (MouseEventArgs e)
    {
        // remove scrolllines scaling, taking care of case scrolllines is 0
        int delta = e.Delta / Math.Max (Math.Abs (SystemInformation.MouseWheelScrollLines), 1);
        base.OnMouseWheel (new MouseEventArgs (e.Button, e.Clicks, e.X, e.Y, delta));
    }
}

Fixes increment of NumericUpDown being 3 instead of 1.
Thanks.
