Unfortunantly, the restriction isn't imposed by POV-Ray in and of
itself. Its a precision problem inherent to how most computers handle
floating point (decimal) numbers. While the numbers show an astronomical
range, the *precision* of the numbers has only a relatively very narrow
range, somewhere in the neighborhood of a few billion truely
representable numbers before you have to start dropping digits. When the
digits are dropped, the calculations are no longer accurate enough and
artifacts do occur.
