这个参考了其它 shape 的实现，发现大部分变换相关的都是在 class 里面直接实现的，目前用途相对单一，后续如果有其它模块的依赖，可以考虑重构一下作为工具函数实现

💡 Background and solution
Detailed questions can be found #1743 .
The root cause is that the camera transformation and element transformation of G are independent, which means that if only the camera is adjusted, the transformation of the canvas element will not change.
However, the implementation of
getBoundingClientRect()ofHTMLtype elements simply calls the DOM API, because the transformation of the cameradivelement as the parent element is also included, which is inconsistent with the calculation logic of the canvas element.Therefore, the camera transformation needs to be eliminated in the implementation of
getBoundingClientRect()ofHTMLtype elements.📝 Changelog
