  (beta 2) bitmap alpha channel, scale and no_image  
From: Carbonaut

32 bit tga and png alpha channel is mixed through out the image. White 3x3
image with top left pixel masked out produces:

 ---     X is masked
|XXX|
|X X|
|XX |
 ---

Also scale and no_image have no effect. Full scene:

plane{z, 1
  pigment{image_map{tga "alpha.tga" once}}
  finish{ambient 1}
  translate<-0.5, -0.5, 0>
  scale 10        // no effect
  no_image        // no effect
}
