That is a good idea, although it would have to be used with a version 
switch. Maybe also provide for switching this off for specific objects, 
something like:
union {
    no_layer_over {
        object {MyObject1 texture {A...}}
    }
    object {MyObject2 texture {B...}
    ...

    texture {C...}
}
MyObject1 would have texture A, and only texture A. MyObject2 would have 
texture B with texture C layered over it. This would be nice if you have 
a CSG with dozens of parts and which has one with a different texture. 
no_layer_over(again, can someone please come up with a better keyword?) 
could act like a kind of union, and contain multiple objects. Perhaps it 
could contain the texture for it's objects itself...
Of course, this would need to be controlled by a #version switch, 
otherwise nearly every CSG ever done will need to be redone.

Also, remove the limitations on layering patterned textures.
