+// This subclass of CPSegmentedControl implements specific behaviour needed by CPTabView, which
+// differs in some ways from normal CPSegmentedControl habits :
+//
+// - all items are enabled
+// - when you select a tab (mouse down, holding) and drag upon another tab, the second one reacts
+//   (showing a pushed state) and can then be selected by releasing the mouse over it.
+// - a delegate has the opportunity to accept or not the selection of an item
