LARGE-TO-SMALL attribute

The default numeric range that a slider can display is small (minimum) to large (maximum). The LARGE-TO-SMALL option allows you to override this default behavior as follows:

When the slider is positioned horizontally, the left-most position on the trackbar displays the maximum value and the right-most position displays the minimum value.
When the slider is positioned vertically, the bottom-most position on the trackbar displays the maximum value and the top-most position displays the minimum value.
