//kasia: Этот файл был изменен в строке 128 и 153 - добавлены значения fps
//          а также в строках с 117-123 - this.div.setStyle и this.div.show() под if(!this.div) {} else{....}
//          это сделано с целью повышения производительности и поддержки IE
//          в случае выхода новой версии window_effects.js, необходимо проверить, работает ли она в IE, и
//          установить другое значение fps
