I am kind of surprised that you switched back from NativeMetafile to Emf, what's
the exact purpose?

This method doesn't really want to render to a metafile, it wants to render to
an EMF (we already have PDF data and we want to be able to print it).  This work
is in preparation for an additional metafile implementation that internally uses
PDFs. Furthermore, the methods of the metafile that this method wants to use are
becoming EMF specific (they don't apply to a PDF implementation of metafile).

         int highest_rendered_page_number) {}
     // Called when no page in the passed in PDF could be rendered.
     virtual void OnRenderPDFPagesToMetafileFailed() {}
