Yeah, me neither. In my view the original problem was reinventing the wheel
on a day-to-day basis. So why would you want to step on that shovel yet
again?
I agree with Laszlo, given that eigen/blas or w/e isn't going in - "just
stick to what is available" seems like a very good advice. On that note
it's probably worth considering "backporting" Qt3D's QTransform and friends
into the gui module, as they're reported to be better optimized, but I
wouldn't go further than that.

Kind regards,
Konstantin.
