//
//  - wxNativeContainerWindowId is the lowest level identifier of the native
//    window, i.e. HWND/GdkNativeWindow/NSWindow (so it's the same as above for
//    all platforms except GTK where we also can work with Window/XID)
//
// later we'll also have
//
//  - wxNativeWindowHandle for child windows (which will be wrapped by
//    wxNativeWindow<T> class), it is HWND/GtkWidget*/ControlRef
