// Contains:
//
// ¥ CScrollerWithArrows
// A class which provides scrolling in one direction, vertical or
// horizontal, by using directional arrows at either end of the
// bar. If the height is longer than the width, we assume vertical
// scrolling (and vice versa).
//
// ¥ CScrollArrowControl
// The arrow control which sends a message to scroll in a particular
// direction. Used by above class.
