Overrides of Drupal's CSS aggregation system. Ensures that files referenced by CSS files are also served from the CDN, according to the CDN module's CSS aggregation rules.

Code

  // Don't override Drupal core's aggregation if this page is not going to use
  // a CDN anyway.

  foreach ($css_groups as $key => $group) {
    switch ($group['type']) {

      // If a file group can be aggregated into a single file, do so, and set
      // the group's data property to the file path of the aggregate file.
      case 'file':
