public CssOptimizer::rewriteFileURI($matches)
Prefixes all paths within a CSS file for processFile().
Note: the only reason this method is public is so color.module can call it; it is not on the AssetOptimizerInterface, so future refactorings can make it protected.
Parameters
array $matches: An array of matches by a preg_replace_callback() call that scans for url() references in CSS files, except for external or absolute ones.
Return value
string The file path.
