将淡入淡出过渡添加到较旧的Unslider脚本？

Question

是否有一种简单的方法可以向此脚本添加淡入淡出过渡？根据它从左到右改变项目的方式，我认为这是不可能的。可能只是使用另一个脚本，但认为获得第二意见并没有什么坏处。

(function(e, t) {
if (!e) return t;
var n = function() {
    this.el = t;
    this.items = t;

        speed: 500,
        delay: 3e3,
        complete: t,
        keys: !t,
        dots: t,
        fluid: t
    };
    var n = this;
    this.init = function(t, n) {
        this.el = t;
        this.ul = t.children("ul");
        this.max = [t.outerWidth(), t.outerHeight()];
        this.items = this.ul.children("li").each(this.calculate);
        this.opts = e.extend(this.opts, n);

    this.calculate = function(t) {
        var r = e(this),
            i = r.outerWidth(),
            s = r.outerHeight();
        n.sizes[t] = [i, s];

看看这个分叉，添加淡入淡出选项：https://github.com/jeremymlane/unslider
