// Summary:
//     Scrollbar control.
// Remarks:
//     Scroll bars provide easy navigation through a long list of items or a
//     large amount of information.  They can also provide an analog representation
//     of current position.  You can use a scroll bar as an input device or
//     indicator of speed or quantity.for example, to control the volume of a
//     computer game or to view the time elapsed in a timed process.
