RenderContext

class RenderContext(val width: Int, val height: Int, val renderOptions: RenderOptions, val lightDirection: Vector = SceneProjector.DEFAULT_LIGHT_DIRECTION.normalize(), accumulatedPosition: Point = Point(0.0, 0.0, 0.0), accumulatedRotation: Double = 0.0, accumulatedScale: Double = 1.0, rotationOrigin: Point? = null, scaleOrigin: Point? = null)

Context for rendering that accumulates transforms through the tree hierarchy

Marked as @Immutable to prevent unnecessary recomposition when instances don't change
