Proposed new feature or change

I tried to look for UI elements that perform things like this

and this

I couldn't find any modules or widgets under visualization to do that, nor could I find any issues that talk about those kinds of features. I was wondering how I could implement those types of UI elements in an open3d project, or if they could be implemented within Open3D.

I know that the C++ branch of Open3D has support for Imgui widgets, but I am working from python, and it seems like ImGuizmo is not really supported in the python bindings for imgui?

Thanks
