/*
	Slimbox (Extended Version 1.3.1.2, 2007-06-07)
	by Peter Klein
	-	Added localization of text values
	-	Support for setting different opacitylevel
	-	Support for changing IFRAME scrolling parameter
	-	Added TYPO3 specific Print & Save options.
	-	Fixed problems with page reload in Print & Save function.
	-	Fixed SWFObject incompability.
	-	Added option to disable numbers.
		
	Slimbox (Extended Version 1.3.1, 2007-02-21)
	by Yukio Arita (http://homepage.mac.com/yukikun/software/slimbox_ex/)
	- 	Support to show external content using iframe.
	- 	Support to set content size. You can add width/height parameters 
		in rev attribute of the anchor url.
		ex1) <a href="image.jpg" rev="width=50%, height=50%" rel="lightbox"><img src="image_thumb.jpg" alt="image"></a>
		ex2) <a href="text.html" rev="width=500, height=300" rel="lightbox">some text here</a>
	- 	Some rendering problem with IE6 is fixed. Now you can use Slimbox in 
		valid XHTML document with XML prolog.
	- Of course, license is same as original.

	Based on:
	Slimbox v1.3 - The ultimate lightweight Lightbox clone
	by Christophe Beyls (http://www.digitalia.be) - MIT-style license.
	Inspired by the original Lightbox v2 by Lokesh Dhakar.
