* Stability fix for dmnsn_bisect_root().Tavian Barnes2010-11-091-4/+9
| | | | | | | When one of the bounds is close to a different root, make sure the result is more accurate than that bound. Otherwise we find the wrong root, and eventually hang. This could be seen with a 1920x1080 render of demo.pov, for example.
