Module primitives 

Core geometric primitives.

Provides fundamental 2D and 3D types used throughout the library.

Design

Points and vectors are mathematically distinct: points live in affine space, vectors in linear space. Operator overloading enforces this:

• Point - Point = Vector
• Point + Vector = Point
• Vector + Vector = Vector
