If you are going to use this code with any of the PDF/PS/SVG/Win32Print
backends it is a good idea to set the JPEG mime data for the image
surface. That way JPEG files will be embedded directly in the output
instead of the backend compressing the image data with lossless
compression. See attached patch.
