Wait a second.  The scene uses max_gradient with evaluate on outdated style
and you end up comparing apples and bananas!!!

I clearly explained when I described the changes that that combination did
not actually use evaluate but only activated the max_gradient message in
beta 6 and any version of isosurfaces (official or unofficial) before beta 7
changed the behavior.  So you are comparing one scene that uses evaluate
(beta 7 and later) and one that never used it (beta 6 and earlier).  The
correct solution is to remove the completely unnecessary "evaluate".
