protected function assetDiff(array $assets, array $start_assets, $diff_function) {
  $diff = $diff_function($assets, $start_assets);

  // Cleanup the resulting array since drupal_array_diff_assoc_recursive() can
  // leave half populated arrays behind.
  foreach ($diff as $key => $entry) {

    // If only the weight was different we can remove this entry.
    if (count($entry) == 1 && isset($entry['weight'])) {
      unset($diff[$key]);
    }
    elseif ($entry != $assets[$key]) {
      $diff[$key] = $assets[$key];
    }
  }
  return $diff;
