I am using the `vkWebViewPort` and the rpc `"viewport.camera.reset"` . Here is the error I get: `"AttributeError("'vtkmodules.vtkRenderingOpenGL2.vtkOpenGLCamera' object has no attribute 'ResetCamera'",)"`

I cannot find how the `ResetCamera` method referenced [here](https://gitlab.kitware.com/vtk/vtk/blob/master/Web/Python/vtkmodules/web/protocols.py#L147) is supposed to work. The view object is a `vtkRenderWindow` in all the examples I could find on internet.  
Thanks for your help.

I made it works by applying the reset on the renderer and not the camera:

```auto
    @exportRpc("viewport.camera.reset")
    def resetCamera(self, viewId):
        """
        RPC callback to reset camera.
        """
        view = self.getView(viewId)
        view.GetRenderers().GetFirstRenderer().ResetCamera()
        self.getApplication().InvalidateCache(view)
        self.getApplication().InvokeEvent('UpdateEvent')

```

Not sure how to directly use the VTK `resetCamera` without this modification.
