  I have an idea of what could this reason possibly be: Since the camera is
inside the sphere, povray has to calculate ray-sphere intersections for
each pixel, just like with ordinary infinite shapes. Perhaps it's faster
to treat it as an infinite surface when you are sure that you really will
need to test it for every pixel (perhaps it has something to do with
vista/light buffers or whatever).
