LcLayerKind enum
Wire format for a single layer, shared between the public FFI surface (engine.h) and every backend implementation (backend.h). This is our generic scene description, not tied to any graphics library.
The Dart side is responsible for:
- resolving stacking order (Layer.zIndex) into plain array order,
- dropping invisible layers,
- flattening the common Layer.transform/size/opacity into these fields. A backend only ever sees a flat array of these and never needs to know about Scene, Layer, or Dart at all.
Adding a new renderable layer kind means adding a value to LcLayerKind, adding its dedicated fields below, and teaching a backend's render_layers to handle the new kind - engine.h's function signature never changes.
