Hmmm... I vaguely recall that somebody (Chris Foster? sounds like the kind of thing he'd do) did an experiment comparing the results of level-to-level resize versus top-to-each-level resize and found the results essentially identical. Maybe "disapproval" was really just advice not to bother if we couldn't demonstrate that the result would be any different? It sounds totally reasonable to me now, especially if it's only triggered by an optional command-line argument (since I'd expect it to be quite a bit more expensive). If you want the feature, please go for it, I have no objection. -- Larry Gritz [email protected]
