  $variables['zebra'] = ($count[$hook] % 2) ? 'odd' : 'even';

    // Load all region content assigned via blocks.
    foreach (array_keys($regions) as $region) {
      // Skip blocks in this region that have already been loaded.
      // This pre-loading is necessary because phptemplate uses variable names different from
      // the region names, e.g., 'sidebar_left' instead of 'left'.
