/**
A Linux-specific class that can embed a foreign X11 widget.
Use this class to embed a foreign X11 widget from other toolkits such as
GTK+ or QT.
For GTK+, create a gtk_plug container and pass the plug's id
(gtk_plug_get_id) to the constructor of this class.
For QT, use the QX11EmbedWidget class and pass the widget's
id (containerWinId()) to the constructor of this class.
Other toolkits or raw X11 widgets should follow the X11 embed protocol:
