mmozeiko, thank you! I mentioned you in repo's commit.
The real deal breaker for me is interpolation: while Gibbs vectors can interpolate just like quat…

Yes you can, I don't mind. WTFPL license :)
mmozeiko, what's the license of your perf test code? Can I add it to my repo under public domain?
Yeah, seeing same results on MSVC2017,
