function _system_theme_settings_validate_path($path) {
    // Absolute local file paths are invalid.

    }
    // A path relative to the Drupal root or a fully qualified URI is valid.
    if (is_file($path)) {
        return $path;
    }
    // Prepend 'public://' for relative file paths within public filesystem.
