Hm, so this is actually the real argument in favor of my original
suggestion (store a vector8 and reinterpret as quats).
Indeed the alignment for vector8's will always be at least as much as
the alignment for quats.

On the other hand, that's a very abstract debate since for now all
simd is 128 bit :)
