This comparison uses the following progressive refinement 
radiosity model:

  patches are .5 units square.

  The light is at 2.999 units instead of 3 to attempt to avoid any strange
  round off errors that might have occured.

  The hemi-cube resolution is 100 on top, 60 on the sides.

  The iterations stop when unshot energy reaches .001 * original_energy.
  
  Light source is four patches.
