/**
* Update the file extension to icon type (e.g., xls => spreadsheet, doc => document) array
*
* Note that the calling function, wp_ext2type, takes an extension and returns an icon type.
* This filter updates the array of possible matches to support the calling function.
*
* Called from /wp-includes/functions.php, function wp_ext2type(). That function is called from
* /wp-admin/includes/ajax-actions.php, function wp_ajax_send_link_to_editor(),
* /wp-admin/includes/media.php, function wp_media_upload_handler(), and
* /wp-includes/post.php, function wp_mime_type_icon(). The first two calls look for "audio"
* and "video" files to call the appropriate filter. The third call assigns the appropriate icon
* to the file for display purposes.
*
* Defined as public because it's a filter.
*
* @since 1.40
*
* @param array The type => ( extensions ) associations.
*
* @return array The updated associations array.
