I've noticed that v3.7 no longer uses max_intersections, in global_settings{}. A
parse warning is issued if max_intersections is included there. Apparently, it
has been deprecated.

The online wiki is missing this new info (ditto in 3.7's included
documentation.) I would suggest a little addendum, to mention this.

The wiki location...
http://wiki.povray.org/content/Reference:Global_Settings

The in-built documentation...
3.4.1.8 Max_Intersections
