Vector types, but instead of being represented as Array-Of-Struct, data is stored as a Struct-Of-Arrays, or SoA.
Data stored in SoA is meant to be processed with SIMD operations, and as such, all arrays are aligned to 16 bytes.
A large subset of the std::Vec interface is supported, as well as some extras
to make writing efficient code more natural.
See the very thorough API Docs.
