NGUI的UIScrollview的优化

之前用UIGrid 发现如果数据量大了。NGUI就会创建大量的GameObject. 这样肯定对性能消耗影响巨大，所以我自己优化了一下。这样效率可以提高很多。当然，优化过后UIGrid还是有一些不足，可惜暂时没有思路，以后有思路了。再接着继续。直接贴代码。

/// CustomGrid,这个类主要做了一件事,就是优化了,NGUI UIGrid 在数据量很多都时候,
///创建过多都GameObject对象,造成资源浪费.
/// 该类需要和 CustomScrollView.cs 以及 CustomDragScrollView.cs一起使用;
/// CustomScrollView 类只上把bounds字段给暴露出来，因为bounds都大小需要在外面设置了.
/// CustomDragScrollView 类 没有修改,
///因为默认都UIDragScrollView 默认里面调用都上UIScrollView
///不能与我们都CustomScrollView兼容.
/// 所以只是将里面都UIScrollView 改为 CustomScrollView.
/// Item 是一个渲染操作类.可以自己定义,或者不要,并没有影响.
