Vector arithmetic in 2D and 3D: add, subtract, scale, dot and cross products, normalisation,
length, angle between, projection and interpolation. Vectors are plain number arrays, so anything
here composes with the geometry APIs without conversion. Use it for directions, normals, offsets and
any math that drives where geometry goes rather than what it is.
