* | Standard compliance. | Tavian Barnes | 2010-11-10 | 1 | -5/+5 |

* | Stability fix for dmnsn_bisect_root(). | Tavian Barnes | 2010-11-09 | 1 | -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. | ||||
