Make multisegment bevel profiles even for all parameters.

The method for calculating points on the profile for non-circles
and non-lines meant that the segments making up an edge had
uneven widths.
Use a numeric search technique to find superellipse evaluation
points that lead to equal-sized chords across the profile.
Also calculate the actual profile points sooner, so that they
don't have to be recalculated again and again.
This also sets up for a possible later feature of arbitrary
profile shapes, set by user.
