### Describe the issue

Hello,

I have a problem with open3d.visualization.gui.Application. It seems that back face culling is not activated, nor can it be activated, when we instantiate a gui.Application.

It seems that Back face culling is active when using "o3d.visualization.Visualizer" but not with "open3d.visualization.gui.Application". In any case, I can't access the rendering options to modify this.

Thank you for your work. This library is very powerful.

### Steps to reproduce the bug

```python
Please see an example with the linked ZIP file:

https://drive.google.com/file/d/1mdkfQvTyeN0-imfflJkyGTB3R_SM2ghH/view?usp=sharing

In the zip, I added a file "tank.gltf" that contains a cylinder with inverted faces that I exported from Blender. I added a file "test_visualiser.py" that contains the Open3D code that uses the "o3d.visualization.Visualizer" class.

I also added the "test_app.py" file which is a copy of the example "vis-gui-py" http://www.open3d.org/docs/release/python_example/visualization/index.html#vis-gui-py and which uses "open3d.visualization.gui.Application":
```

### Error message

_No response_

### Expected behavior

Back face culling should be enabled by default and there should be a method to change this state.
