/**
 * Implementation of hook_media_format_form_prepare_alter(&$form, &$form_state, $file)
 *
 *
 * Alter the WYSIWYG view mode selection form.
 *
 * Similar to a form_alter, but runs first so that modules can add
 * fields specific to a given file type (like alt tags on images) before alters
 * begin to work on the fields.
 *
 * @param array $form
 *   An associative array containing the structure of the form.
 * @param array $form_state
 *   An associative array containing the current state of the form.
 * @param object $file
 *   A file entity.
 *
 * @see media_format_form()
