Erm... my fix was for pov-ray for windows, too. Look in the windows
directory for a file called config.h. Change epsilon and add those
other two #defines. Recompile. Your spheres now render the same
size. But who knows why epsilon was so big or what else this change
might break in heightfields etc.
Compared to using an ellipsoid intersection routine, I suppose the
speedup is probably pretty good.
