Returns the minimum exponent such that vertices will not move by more
than "snap_radius". This can be useful when choosing an appropriate
exponent for snapping. The return value is always a valid exponent
(out of range values are silently clamped).
If you want to choose the exponent based on a distance, and then use
the minimum possible snap radius for that exponent, do this:
