-// 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).
