Just to make sure I've got this right, I'm currently attempting to
render an image_map on a box in my scene.  It's imperitave that the
resulting image is traced so each pixel of the image_map fills exactly
one pixel of my new picture.  Would this be the proper settings?

camera {
  orthographic
  location <0,0,-1>
  look_at  <0,0,0>
  right 1*x
  up 1*y
}

box {
   <-0.5, -0.5, 0.001>, <0.5, 0.5, 0.001> 
   ...
}


My image_map will of course need to be translated -0.5 to get it
centered in my box properly, but am I right in assuming this will
reproduce my image exactly?
