/**
 *	UI Layout Plugin: Slide-Offscreen Animation
 *
 *	Prevent panes from being 'hidden' so that an iframes/objects
 *	does not reload/refresh when pane 'opens' again.
 *	This plug-in adds a new animation called "slideOffscreen".
 *	It is identical to the normal "slide" effect, but avoids hiding the element
 *
 *	Requires Layout 1.3.0.RC30.1 or later for Close offscreen
 *	Requires Layout 1.3.0.RC30.5 or later for Hide, initClosed & initHidden offscreen
 *
 *	Version:	1.1 - 2012-11-18
