I'm trying to interact with `javafx.scene.Node`'s public void snapshot(Callback<SnapshotResult, Void> callback, SnapshotParameters params, WritableImage image). However, since Callback is expected to return java.lang.Void... what do I do? Kotlin is upset because I'm returning Unit, but Void cannot be instantiated
