 * MozContainer

 * This class serves three purposes in the nsIWidget implementation.

 *   - It provides objects to receive signals from GTK for events on native

 *     windows.

 *   - It provides GdkWindow to draw content on Wayland or when Gtk+ renders

 *     client side decorations to mShell.
