/**
* {@link ReplayRenderer} that rewrites URLs found in CSS resource and inserts
* {@code jspInserts} at the top of the document.
* <p>This ReplayRenderer searches for URLs in CSS document, and rewrites
* them with {@link ResultURIConverter} set to {@link TextDocument}.</p>
* <p>In fact, this class simply calls {@link TextDocument#resolveCSSUrls()}
* for URL rewrites. Note that ResultURIConverter argument to {@code updatePage}
* method is unused.</p>
* <p>This class may be used in both Archival-URL and Proxy mode, despite its
* name, by choosing appropriate {@code ResultURIConverter}.</p>
* <p>There's separate classes for rewriting CSS text embedded
* in HTML. They use their own code for looking up URLs in CSS.</p>
