+ * implements nsIWidget. We hand this around layout and plugins code. Anything
+ * not dealt with via PluginWidgetProxy falls through to PuppetWidget. Native
+ * widget exists on the chrome side (PluginWidgetParent) attached to the
+ * browser window as a child. Window management calls are forwarded from
+ * PluginWidgetProxy to PluginWidgetParent over this interface.
+ *
+ * Note lifetime management for PluginWidgetProxy (the plugin widget) and the
+ * connection (PluginWidgetChild) are separated. PluginWidgetChild will
+ * be torn down first by the tab, followed by the deref'ing of the nsIWidget
+ * via layout.
