Another Raytracer

here's the output of a raytracer in python, called yopyra, by carlos gonzales, after being compiled by shedskin. the speedup is about the same as for the pygmy raytracer, that is part of the unit tests (for this picture it is about 60). I will probably add this program to ss-progs, but I need to remove one hack to support it, and bearophile (who sent me the raytracer) is still adding some nice features, like the ability to read scenes from a file, and render parts of a picture, so it's easy to put those multiple cores to use..
