jsn_load.rs

//! Load a `.jsn` scene exported from the Jackdaw editor.
//!
//! 1. Add `jackdaw_runtime` to your `Cargo.toml`
//! 2. Add `JackdawPlugin` to your app
//! 3. Spawn a `JackdawSceneRoot` with an asset server load
//!
//! The scene includes lights, brushes, and any other entities
//! saved from the editor. You only need to provide a camera.
