Request: Ergonomically convert between Euclidean vectors and homogeneous coordinates

Request: Ergonomically convert between Euclidean vectors and homogeneous coordinates: a task in LegoFlow-SWE (Harbor dataset). Currently, users must manually write error-prone code to convert a homogeneous Vec4 to a Euclidean Vec3 by doing let v3 = v4.xyz() / v4.w; and there is no direct…
