When building WebKit with PLUGIN_PROXY_FOR_VIDEO, the MediaPlayer is not destroyed and recreated when loading a new movie to avoid the expensive plug-in setup and handshake each time a movie is loaded. Because the current movie may still be loading, the plug-in proxy method cancelLoad should be called to give it a signal that a new movie will be loading.
