Not entirely; for some stuff UberPOV still only provides POV-Ray's
biased algorithms; I haven't tackled media, dispersion and caustics yet,
and there might be more I haven't even thought of so far.
But yes, it is my intention for UberPOV to ultimately provide unbiased
algorithms for these effects as well. Alongside POV-Ray's biased
algorithms, allowing the user to choose whatever they prefer.
