 // SubmenuView has the following responsibilities:
 // . It positions and sizes all child views (any type of View may be added,
 //   not just MenuItemViews).
 // . Forwards the appropriate events to the MenuController. This allows the
 //   MenuController to update the selection as the user moves the mouse around.
 // . Renders the drop indicator during a drop operation.
 // . Shows and hides the window (a WidgetWin) when the menu is shown on
 //   screen.
 //
 // SubmenuView is itself contained in a MenuScrollViewContainer.
 // MenuScrollViewContainer handles showing as much of the SubmenuView as the
 // screen allows. If the SubmenuView is taller than the screen, scroll buttons
 // are provided that allow the user to see all the menu items.
