IMPORTANT: I had to revert Finn Bock's changes to the PDFRenderer (dated 2004/09/22 13:22:16), otherwise leaders with svg use-content produce errors in the pdf output. There isn't any run-time error, but when I try to open the pdf file, I get these warnings: - There was an error processing a page. Wrong operand type. - Illegal operation 'q' inside a text object. - Wrong operand type. and the page with the svg leaders is left empty. I think it could be something involving the saveGraphicsState() method.
I've just now fixed this issue so that your patch work with the PDFRenderer.
