Normals visualization in gui::Window app

[vovo-4K]

I found several concurrent ways to create GUI applications using Open3D.
Simple Visualizer has the ability to set RenderOptions to enable normals visualization.
But how to enable normals rendering on gui::SceneWidget?

Upd. I'm using C++ API. C++ documentation is not user friendly a bit

Ok. I found a workaround with the manual creation of geometry::LineSet and adding it as a separate Geometry entity to the scene.
But is there any more elegant way to visualize normals from geometry::PointCloud normals_ field?

Hi @vovo-4K we are migrating Open3D visualization to a new backend, with support for creating GUIs. The new functionality is in the gui:: and rendering:: namespaces. As such some features (such as the hedgehog normals visualization) are not available yet. Please open a feature request.
