* Standard compliance.Tavian Barnes2010-11-107-36/+59
| | | | Apparently ssize_t isn't a standard type...
* Use Newton's method when the root bound is degenerate.Tavian Barnes2010-11-102-5/+39
|
* 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.
* Don't just use quick_color for solid_color pigments.Tavian Barnes2010-11-092-3/+24
| | | | | quick_color should be able to be used to change an object's color for low-quality-renders.

|
* Change initial array capacity to 2.Tavian Barnes2010-10-211-11/+11
| | | | | A quick experiment shows that arrays average less than 2 elements, and this helps a bit with the memory-hogginess of the parser.
