+/**
+ * CSwtScrollBar
+ *
+ * In eSWT all scrollbars must be non window owing the main reason being that
+ * the scrollbars must draw at exact same time with the parent control. This
+ * is especially essential in ScrolledComposite. If the scrollbars would be
+ * window owing, they would draw too much ahead of the parents creating an
+ * ugly visual effect when flicking the ScrolledComposite.
+ * The drawback of having non window owing scrollbars is too many paint events
+ * which affects on the speed of kinetic scrolling in lists.
