The IsDirectionReversed property determines whether the direction of
increasing Value is reversed from the default direction.
By default the property is false and values increase from left to right
for a horizontal slider.
For a vertical Slider the values increase from bottom to top. When you set the
IsDirectionReversed property to true, the direction of
increasing value reverses.
