4.7.8.9.1 The once Option
Normally there are an infinite number of repeating image maps,
bump maps or material maps created over every unit square of the
x-y-plane like tiles. By adding the once keyword after a file
name you can eliminate all other copies of the map except the one
at (0,0) to (1,1). In image maps, areas outside this unit square
are treated as fully transparent. In bump maps, areas outside
this unit square are left flat with no normal modification.  In
material maps, areas outside this unit square are textured with
the first texture of the texture list.

For example:

  image_map {
    gif "mypic.gif"
    once
  }
