SceneView class

A self-contained widget that renders a SceneController and feeds it input.

Pointer events are forwarded to SceneController in view/screen coordinates (as received from PointerEvent.localPosition). The controller converts them to scene coordinates using scene.camera.offset.

The view repaints via SceneController as a CustomPainter notifier.
