 /* TODO(caryclark): The set up of PluginInstance::PrintPDFOutput may result in
    rasterized output.  Even if that flow uses PdfMetafileCg::RenderPage,
    the drawing of the PDF into the canvas may result in a rasterized output.
    PDFMetafileSkia::RenderPage should be not implemented as shown and instead
    should do something like the following CL in PluginInstance::PrintPDFOutput:
