Overview

A node whose children live in world space and are drawn through a Camera: it wraps their draw in renderer.translated(-camera.x, -camera.y), so the camera's offset maps the world onto the screen. The children never know about the camera — they draw at their own absolute (world) origin, and the view transform does the rest. The owning scene drives the camera (e.g. centring it on the player); this node only applies it.

The offset is a draw-time transform, not a position baked into a node, so the same world can later be drawn through several cameras (split-screen) by repeating the pass under different offsets/clips.
