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

 * 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.
 *
 * The GD rendering backend is a little different than PDFLib and
 * CPDF. Several features of CPDF and PDFLib are not supported or do
 * not make any sense when creating image files.  For example,
 * multiple pages are not supported, nor are PDF 'objects'.  Have a
 * look at {@link GD_Adapter} for more information.  GD support is
 * experimental, so use it at your own risk.
