希望 wasm 版本支持自定义测量函数，类似 Yoga 的 setMeasureFunc

binding.cc 中该部分代码被注释了

是否不支持 position 类型为 sticky、fiexed ？

有具体的DEMO吗

有没有coding的IDE？以及一套可以看到界面（iOS、Android）的完整的流程？

Support Windows Platform

Is trere any plan support windows platform?

Percent value support

Very awesome library.

Is there a way to implement the percentage value support?

For example the width and height values would be percentage too.

Is it possible in the near future?

Thank for answers.
