Yeah I probably wouldn't put anything that high level in a standard
library. Everyone will want a slightly different flavour.
I think linear algebra with vectors, matrices, quats is about the fair
extent of a std lib. That stuff is pretty un-debatable, but beyond that, it
starts getting very subjective or context specific. Better left for higher
level libraries that may also integrate with renderers/physics systems/etc.
