- 原生平台上支持 Spine 与其它组件合批
- tiledMap 生成的 Label 好像不能使用 CacheMode,然后考虑对其进行一些优化
+- 动态图集支持预乘纹理
- 补充原理文档
- Char 模式因为 bleed 问题只能复用完全相同宽高的区域,试着增加一个选项,能够先用空纹理覆盖,之所以做选项是不知道性能消耗大不大
- 新增静态合批:在一个节点树的根节点挂上一个组件,该组件会快照这个节点树并显示为一张图片,然后只接管渲染,不影响其它逻辑,也可以选择直接删除掉被快照的所有节点

-[Docusaurus blogging features](https://docusaurus.io/docs/blog) are powered by the [blog plugin](https://docusaurus.io/docs/api/plugins/@docusaurus/plugin-content-blog).
-
-Simply add Markdown files (or folders) to the `blog` directory.
-
-Regular blog authors can be added to `authors.yml`.
-
-The blog post date can be extracted from filenames, such as:
-
-- `2019-05-30-welcome.md`
-- `2019-05-30-welcome/index.md`
-
-A blog post folder can be convenient to co-locate blog post images:
-
-![Docusaurus Plushie](./docusaurus-plushie-banner.jpeg)
-
-The blog supports tags as well!
-
-**And if you don't want a blog**: just delete this directory, and use `blog: false` in your Docusaurus config.
