I was rendering a scene using the SuperPatch, and when I looked at the
rendering statistics, they indicated that there was a CSG Merge in the
scene, when I know that I didn't put one in.  Is this really an error, or is
it just the way POV does things?  Here is the simplest code I could create
that has this possible error:

#include "colors.inc"

#declare MainObject =
difference{
 union{
  box{ <1699,360,800>,<1001,375,900> pigment{ Green } }
 }
 //Note: This intersection appears to be the merge.
 intersection{
  box{ <1700,366,848.5>,<1000,369,851.5> }
  cylinder{ <1701,363,850>,<1000,363,850>,5.5 }
  pigment{Red}
 }
}

#declare camera1 = camera{
 location <2100,380,690>
 look_at <1900,370,770>
 angle 20
}

light_source{ y*10000000 White*1.8 }
light_source{ <1150,367,850> White }//Tunnel light
light_source{ <1600,367,850> White }//Tunnel light

camera{ camera1 }

object{ MainObject }
