Depending on how complex your CSG is, it might be possible to make a 
copy of the whole CSG object (without textures) and make it marginally 
larger than the original. Then you can apply a mainly transparent 
texture with your decals applied.

It's not an ideal solution though, I've come up against that before when 
making a wooden table where the top was made up of several different 
bits of wood. In my case it was easy to add an additional transparent 
object just above the surface, but in general it's not always that easy.

Personally I think it's counter-intuitive that a "texture" statement at 
a higher level wouldn't act on *all* lower level objects (obviously 
making them redundant if totally opaque). If I apply a translate, rotate 
etc it acts on the whole thing, not only on sub-objects that haven't 
been translated/rotated already.

If needed there should be a special flag to say "don't apply this 
texture to sub-objects that are already textured".
