// pair of files).
// This function is then called from updatesite.class.php (UpdateSite class) 'previewpage' function. 'previewpage' check to see
// that the function exists. If it does not exist then a message is presented and the user is given the option to proceed to the
// post page without a preview option.
// If this function does exist it is passed the "$this" of the UpdateSite class, the id of the item, the page name, itemname, and
// the title and bodytext text.
// It presents an <iframe> that is filled via blob-datauri logic and a form that has a 'create' and 'discard' button.
// The form's action is $classthis->self so the form goes back to updatesite.class.php with
// page=Post so updatesite.class.php performs the Post.
// The iframe has the full page of the 'page' file with the insert (that is $item has our new text).
// The iframe is '<iframe id="frame" style="width: 100%; height: 100%;"
// src="a-data-uri"></iframe>'.
