     * The PDF rendering backend to use

     * fall back on CPDF. 'GD' renders PDFs to graphic files. {@link

     * based on this setting.
     *
     * Both PDFLib & CPDF rendering backends provide sufficient rendering
     * capabilities for dompdf, however additional features (e.g. object,
     * image and font support, etc.) differ between backends.  Please see
     * {@link PDFLib_Adapter} for more information on the PDFLib backend
     * and {@link CPDF_Adapter} and lib/class.pdf.php for more information
     * on CPDF. Also see the documentation for each backend at the links
     * below.

     * not make any sense when creating image files.  For example,
     * multiple pages are not supported, nor are PDF 'objects'.  Have a
