* init阶段核心仅仅是根据xml和css创建了节点树
* 要实现真正的渲染，需要调用 layout 函数，之所以将 layout 单独抽象为一个函数，是因为 layout 应当是可以重复调用的
* 比如改变了一个元素的尺寸，实际上节点树是没变的，仅仅是需要重新计算布局，然后渲染
* 一个完整的 layout 分成下面的几步：
* 1. 执行画布清理，因为布局变化页面需要重绘，这里没有做很高级的剔除等操作，一律清除重画，实际上性能已经很好
* 2. 节点树都含有 style 属性，css-layout 能够根据这些信息计算出最终布局，详情可见 https://www.npmjs.com/package/css-layout
* 3. 经过 Layout 计算，节点树带上了 layout、lastLayout、shouldUpdate 布局信息，但这些信息并不是能够直接用的
* 比如 layout.top 是指在一个父容器内的 top，最终要实现渲染，实际上要递归加上复容器的 top
* 这样每次 repaint 的时候只需要直接使用计算好的值即可，不需要每次都递归计算
* 这一步称为 layoutChildren，目的在于将 css-layout 进一步处理为可以渲染直接用的布局信息
* 4. renderChildren：执行渲染
* 5. bindEvents：执行事件绑定
