[jitter] multiples and shaders

This makes sense. But it is kind of splitting hairs. Is there a way  
to have the same shader for M objects of jit.multiple, but with N  
different setting for the params for the shader? Or is this better  
done with a poly of objects and shaders or better yet jit.lua? I  
guess the question is in what ways can one introduce variation with  
jit.multiple?

cheers,
