To see it in action run the example in `examples` with `cargo run --example xr`

## Troubleshooting

- Make sure, if you're on Linux, that you have the `openxr` package installed on your system.
- I'm getting poor performance.
    - Like other bevy projects, make sure you're building in release (example: `cargo run --example xr --release`)
