/**

 * @file

 * Default theme implementation to display a file.

 *

 * Available variables:

 * - $label: the (sanitized) file name of the file.

 * - $content: An array of file items. Use render($content) to print them all,

 *   or print a subset such as render($content['field_example']). Use

 *   hide($content['field_example']) to temporarily suppress the printing of a

 *   given element.

 * - $user_picture: The file owner's picture from user-picture.tpl.php.

 * - $date: Formatted added date. Preprocess functions can reformat it by

 *   calling format_date() with the desired parameters on the $timestamp

 *   variable.

 * - $name: Themed username of file owner output from theme_username().

 * - $file_url: Direct URL of the current file.

 * - $display_submitted: Whether submission information should be displayed.

 * - $submitted: Submission information created from $name and $date during

 *   template_preprocess_file().

 * - $classes: String of classes that can be used to style contextually through

 *   CSS. It can be manipulated through the variable $classes_array from

 *   preprocess functions. The default values can be one or more of the

 *   following:

 *   - file-entity: The current template type, i.e., "theming hook".

 *   - file-[type]: The current file type. For example, if the file is a

 *     "Image" file it would result in "file-image". Note that the machine

 *     name will often be in a short form of the human readable label.

 *   - file-[mimetype]: The current file's MIME type. For exampe, if the file

 *     is a PNG image, it would result in "file-image-png"

 * - $title_prefix (array): An array containing additional output populated by

 *   modules, intended to be displayed in front of the main title tag that

 *   appears in the template.

 * - $title_suffix (array): An array containing additional output populated by

 *   modules, intended to be displayed after the main title tag that appears in

 *   the template.

 *

 * Other variables:

 * - $file: Full file object. Contains data that may not be safe.

 * - $type: File type, i.e. image, audio, video, etc.

 * - $uid: User ID of the file owner.

 * - $timestamp: Time the file was added formatted in Unix timestamp.

 * - $classes_array: Array of html class attribute values. It is flattened

 *   into a string within the variable $classes.

 * - $zebra: Outputs either "even" or "odd". Useful for zebra striping in

 *   listings.

 * - $id: Position of the file. Increments each time it's output.

 *

 * File status variables:

 * - $view_mode: View mode, e.g. 'default', 'full', etc.

 * - $page: Flag for the full page state.

 * - $is_front: Flags true when presented in the front page.

 * - $logged_in: Flags true when the current user is a logged-in member.

 * - $is_admin: Flags true when the current user is an administrator.

 *

 * Field variables: for each field instance attached to the file a corresponding

 * variable is defined, e.g. $file->caption becomes $caption. When needing to

 * access a field's raw values, developers/themers are strongly encouraged to

 * use these variables. Otherwise they will have to explicitly specify the

 * desired field language, e.g. $file->caption['en'], thus overriding any

 * language negotiation rule that was previously applied.

 *
