-////////////////////////////////////////////////////////////////////////////////
-// Widget class
-//
-//  Encapsulates the platform-specific rendering, event receiving and widget
-//  management aspects of the UI framework.
-//
-//  Owns a RootView and thus a View hierarchy. Can contain child Widgets.
-//  Widget is a platform-independent type that communicates with a platform or
-//  context specific NativeWidget implementation.
-//
-//  A special note on ownership:
-//
-//    Depending on the value of the InitParams' ownership field, the Widget
-//    either owns or is owned by its NativeWidget:
-//
-//    ownership = NATIVE_WIDGET_OWNS_WIDGET (default)
-//      The Widget instance is owned by its NativeWidget. When the NativeWidget
-//      is destroyed (in response to a native destruction message), it deletes
-//      the Widget from its destructor.
-//    ownership = WIDGET_OWNS_NATIVE_WIDGET (non-default)
-//      The Widget instance owns its NativeWidget. This state implies someone
-//      else wants to control the lifetime of this object. When they destroy
-//      the Widget it is responsible for destroying the NativeWidget (from its
-//      destructor).
