Yes, but ignore the beta 7 implementation details as they are not complete
yet.  The main idea was to get some feedback on the changes, but of course I
didn't take into account the problem that was left in there.

What is happening is that the "adaptive max_gradient technique" as Mr.
Suzuki calls it, is now always used partially.  Unfortunately this causes
the max_gradient to grow and thus cause the slowdown people report with
evaluate.

I have a good idea how the code works, but not what the individual values of
evaluate will exactly do to what surface, if that is what you are asking.
