Is it possible to have a `"key_hold"` event that is triggered when a key is held in the "down" position? It seems like the `"key_down"` event is only triggered once...

`WgpuRenderer.get_pick_info()` does not appear to return `ndc`

1

`WgpuRenderer.get_pick_info(pos)` does not appear to return ndc, as mentioned in the docstring. To return the ndc wouldn't it need to have access to the camera matrix? https://github.com/pygfx/pygfx/blob/5ba70b8021ddbc3c35bad3afdbd9e26de6ab27d1/pygfx/renderers/wgpu/_renderer.py#L642-L649 This isn't a...

Integration with wgpu-py

3

I'm wondering how this could be integrated with [`wgpu-py`](https://github.com/pygfx/wgpu-py), I see that all the current integrations use [`OpenGL`](https://github.com/pyimgui/pyimgui/tree/master/imgui/integrations). The usecase is that it could then be used with [`pygfx`](https://github.com/pygfx/pygfx). I'm...
