Viewsource is now based on XML. These changes make viewsource 2X faster, 30% smaller (in obj code), and uses between 30-60% less markup overhead. This update also enables stylesheet usage on viewsource, which is controlled by the viewsource namespace in html.css. Also, note that viewsource remains (and always has been) fully incremental. Remaining performance issues are in contentsink as shown in quantify runs. git-svn-id: svn://10.0.0.236/trunk@50938 18797224-902f-48f8-a5cc-f745e15eee43
