/**
* dhtmlPopWindow v0.1
*	By: me@daantje.nl
*	Mon Jun 26 14:33:04 CEST 2006
*
*	DESCRIPTION:
*		Wrote this script, cause I needed something to fool the popup killers.
*		This script pops a DHTML div with an iframe with the given page.
*		The popped window appears always in the center of the window/frame.
*		But it's draggable across the window/frame. All the layout can be done
*		with a CSS style sheet. This is what I needed till now, but this script
*		could be somewhat better. Check the todo list...
*

*	SUPPORT:
*		Check http://www.daantje.nl
*
*	BUGS AND PATCHES:
*		Please mail me any bugs and/or patches!
*
*	TODO LIST:
*		When you fiel the need to help...
*		- Add scale window funtionality.
*		- Make close button configurable.
*		- Add configurable window placement.
*		- Add configurable window target name.
*		- Add multiple window support.
