Comment 11 for bug 1118663

thanks for the update, I will try to look at it this weekend, or at least within the next week.

With respect to the flatness calculation in cspsubdiv, I would recommend against committing or proposing a new version of the code that implements this, unless the code is different in some fundamental way. If there is a deficiency in the existing calculation, then the normal procedure is to submit a separate bug report on this issue, so that it can be evaluated and confirmed and applied to all the calculations that depend on this flattening subroutine.
