`iced_native` takes [`iced_core`] and builds a native runtime on top of it, featuring:
- A custom layout engine, greatly inspired by [`druid`]
- Event handling for all the built-in widgets
- A renderer-agnostic API
To achieve this, it introduces a bunch of reusable interfaces:
- A `Widget` trait, which is used to implement new widgets: from layout requirements to event and drawing logic.
- A bunch of `Renderer` traits, meant to keep the crate renderer-agnostic.
- A `Windowed` trait, leveraging [`raw-window-handle`], which can be implemented by graphical renderers that target _windows_. Window-based shells (like [`iced_winit`]) can use this trait to stay renderer-agnostic.
