Notes:

 resolution 513x513 pixels, but 513x513 = 263169 primary rays
  according to SPD document

 Implementations:

 povray - version 3.00b.Linux.gcc,
          compiled on Linux, RedHat 5.1, ELF, gcc version 2.8.1
          Options: -O2 -finline-functions

 golem - version 1.00 ( -revision version-1-0-8 under CVS)
