  Compound Eyes

       This is a really a tough case. Down-sampling it to 480x720 and under
       different algorithms there may easilly show...

       a) moire patterns on the compound eyes
       b) increase in overall brightness (probably due to haloing)
       c) lose of rainbow-shine
       d) aliasing on the hairs or, in contrast, blurriness of the hairs
