* PPluginWidget - a nsIWidget'ish protocol for windowed plugins in e10s.
* On windows and linux we create native widgets in chrome which we then manage
* from content. On the content side there's PluginWidgetProxy which
* 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.
