  Background image

Hi all,

    I'm working on a small project at the moment, and find that I need to use an
bitmap as
a background image. It looks like I'm going to have to map this image to a plane, and
then
mess about positioning and scaling the plane so that the image fits the screen
perfectly.
Too large, and the bitmap will pixellate, or, if I use interpolate, blur.
    It struck me that having an image_map available from within the 'background'
keyword
would be very usefull ie

background { rgb <1,.3,.4> // colour that will only be visible in
refraction/reflection
      image_map { gif "MyPic.gif"}
                }

What do you think?

Also, why can't we have a global map that only shows up in reflections ( as in Imagine
)?
Using the two methods combined would work well.
