/**
 * AutoSizeiFrame
 * Snippet to automatically resize an iFrame to display the full height of its content.
 * Original code borrowed from the IFrame SSI script II by Dynamic Drive DHTML code library (http://www.dynamicdrive.com) 
 * Ported to MODx by Guillaume Pointel
 * Version: 0.1 (January 2007)
 * License: GPL
 *
 * History:
 * - 0.1 - First initial public release
 *
 * Installation:
 * Copy the contents of the file into a new snippet named AutoSizeiFrame
 *
 * Configuration:
 * You could use it to display the full heigth of a document embed in your page using the "view port" widget, and just calling the TV in your content area. In this case, recommended settings are :
 * - "Stretch To Fit" and "Autosize" set to "yes", rest as default.
 * - "Input type" : URL
 * - check the correct template access
 * Then call this TV and the snippet in the page where you want your iframe put, fill in the URL in the Document Editor
 * Warning : the script cannot probe and detect the height of pages from external domains.
 * You can also put in your own frame : <iframe id="myframe" src="externalpage.htm" scrolling="no" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" style="overflow:visible; width:100%; display:none"></iframe>
 * Finally, you can also load another document in your iframe using a link in your main document using the javascript "loadintoIframe" function :: <a href="javascript:loadintoIframe('myframe', 'external.htm')">Link</a>
 *
 * Parameters:
 * - $iframeids - Input the name/IDs of the IFRAMES you wish to dynamically resize to match its content height. Separate each ID with a comma. Examples: myframe1,myframe2 or myframe. Be sure to put the exact same ID/name as the view port widget.
 * - $iframehide - (optional) yes/no : Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers recommended - default is no, will display the iframe but not resize it - be sure not to put the "Scrollbars" on "no")
 *
 * exemple : [[AutoSizeiFrame? &iframeids=ID_ViewportWidget_1,ID_iframe_2]]
