gecko-dev/layout/base/nsDocumentViewer.cpp
tbogard%aol.net eb96099e6d 1.) WebShell no longer implements nsIScriptContextOwner. 
2.)  WebShell now implements the new nsIScriptGlobalObjectOwner.
3.)  WebShell supports GetInterface to nsIScriptGlobalObject.
4.)  Documents no longer carry around a reference to nsIScriptContextOwner.  Instead they hold on to a nsIScriptGlobalObject.  nsIDocument::GetScriptContextOwner has now become nsIDocument::GetScriptGlobalObject().  Same change to the set methods.
