// Ladislav Zigo,lacoz@web.de
/*
Updates by Moses Gunesch - www.MosesSupposes.com - May 2005 [all updates marked with search string: -(MosesSupposes)- ]
	Added extensions:	invertColorTo, tintTo, sizeTo
						pauseTween, unpauseTween, isTweenPaused, ffTween, rewTween,
						(global shortcuts:) pauseAllTweens, unpauseAllTweens, stopAllTweens
	TextField support, String for relative values, comma-delimited strings for mult props,
		support for single endval : mult props, new cleanUp routine, autoStop affects all props
	<<Complete notes in $tweenManager.as>>
