I was checking the code flow but I am confused in this part how the **src/vtk/cropwidge** t folder is connecting the **src/components/tools/croptool** folder I have checked the flow but I am unable to find the connection between these two folders

1. how **src/vtk/CropWidget** is connect to **src/components/tools/CropTool**

2. The code implemented inside src/vtk/CropWidget files behavior.js & index.js is different compared to the vtk.js github files.

(Context: Kitware Glance)

1. The cropProxy ([glance/script.js at master · Kitware/glance · GitHub](https://github.com/Kitware/glance/blob/master/src/components/tools/CropTool/script.js#L40)) is a proxy wrapper object that holds a reference to the crop widget. This proxy wrapper is defined declaratively here: [glance/proxy.js at master · Kitware/glance · GitHub](https://github.com/Kitware/glance/blob/master/src/config/proxy.js#L88-L91)

2. The CropWidget files inside src/vtk extend the one from vtk.js. Other than the minor tweaks, the two are the same.
