Crate tuppu_scene 

Scene graph with exact coordinates and motor transforms.

This crate provides:

• Node: Scene graph node with transform, material, geometry
• Scene: Container for nodes with hierarchy management
• Transform: Motor-based rigid transformations
• Camera: Isometric and orthographic projection
• Geometry: Point, Vector, Plane, Circle, etc.
• Material: Color and rendering properties
• [Interaction]: Hit testing and drag constraints

Design Principles

1. Exact coordinates: All positions use [Scalar] from tuppu-scalar
2. Motor transforms: Rigid motions via geometric algebra
3. Stable IDs: NodeId persists across frames for incremental rendering
4. Snap-to-exact: Input quantization at boundaries
