My array seems to work. We came from powers of two. I don't know why
that is important. sqrt(2) is a fractional power of two, not a true
integral power of two. So this is an overly theoretical goal.
The user experience is what's important here. So until we find bad
*actual experiences* with the code I proposed, I think we should run
