Wouldn't it be logical to use it as an image type in image_map ?

object {
       Stuff
       pigment {
               image_map {
                         portal {
                                camera {...}
                                }
                         map_type ...
                         once
                         }
               }

       }

The resulting pigment would be mapped onto 0,1 area, as usual, and
one could use image_maps keywords to control how the "image" (though
not a bitmap) is mapped onto the object.  If someone wants to make
a normal of it, there's the "pigment pattern" feature.

Just my 2 rays.
