-// RootView class
-//
-//  The RootView is the root of a View hierarchy. A RootView is attached to a
-//  Widget. The Widget is responsible for receiving events from the host
-//  environment, converting them to views-compatible events and then forwarding
-//  them to the RootView for propagation into the View hierarchy.
-//
-//  A RootView can have only one child, called its "Contents View" which is
-//  sized to fill the bounds of the RootView (and hence the client area of the
-//  Widget). Call SetContentsView() after the associated Widget has been
-//  initialized to attach the contents view to the RootView.
-//  TODO(beng): Enforce no other callers to AddChildView/tree functions by
-//              overriding those methods as private here.
-//  TODO(beng): Clean up API further, make Widget a friend.
-//  TODO(sky): We don't really want to export this class.
