-// NativeWidgetWin
-//  A Widget for a views hierarchy used to represent anything that can be
-//  contained within an HWND, e.g. a control, a window, etc. Specializations
-//  suitable for specific tasks, e.g. top level window, are derived from this.
-//
-//  This Widget contains a RootView which owns the hierarchy of views within it.
-//  As long as views are part of this tree, they will be deleted automatically
-//  when the RootView is destroyed. If you remove a view from the tree, you are
-//  then responsible for cleaning up after it.
