2) Adds a couple of new methods and an attr to nsIWebBrowserPrint (navigate, is frameset, & exitPP)
3) Removes all but one method from nsIContentViewerFile.idl/h the remaining call is for print regression testing
4) Removes the "static" implementation of nsIContentViewerFile.h
5) Fixed up nsIContentViewerFile.idl and turned it back on so it is now generating the header file
6) Removed all uses of nsIContentViewerFile.h except for the WebCrawler (uses it for Printing Regression testing)
7) nsDocumentViewer.cpp now implements nsIWebBrowserPrint.idl this makes it easier to add new print functionality in one place
8) You can now ask an instance of the ContentViewer for a nsIWebBrowserPrint to do printing (it retruns the nsIWebBrowserPrint interface implemented by the nsDocumentViewer)
9) Anybody who was using nsIContentViewerFile to print will now use nsIWebBrowserPrint
10) You can now do a "GetInterface()" on a GlobalWindow for a nsIWebBrowserPrint
11) The browser UI now uses the GetInterface on the GlobalWindow to get a nsIWebBrowserPrint object to do printing and this can be used for all printing functionality
