Just turning on antialising for the 640x480 version changed the
rendering time drastically...


Render Time:
  Photon Time:      No photons
  Radiosity Time:   No radiosity
  Trace Time:       0 hours  5 minutes 35 seconds (335.974 seconds)
              using 2 thread(s) with 384.572 CPU-seconds total
POV-Ray finished
-
CPU time used: kernel 0.78 seconds, user 384.84 seconds, total 385.62
seconds.
Elapsed time 337.00 seconds, CPU vs elapsed time ratio 1.14.
Render averaged 911.56 PPS (796.64 PPS CPU time) over 307200 pixels.
