I think what is happening is that POV uses radiosity to compute the
ambient light at each point, and ambient light has no direction. POV
can't include the normal in the calculations, because the samples don't
all go in the same direction. And it can't store the directions of each
individual sample ray, that would slow calculations down a *lot* and
use much more memory.
