That's an interesting idea, haven't thought of that, but is sounds a bit
hackish. I mean, how do you select the appropriate layer depth so that
you get maximum of one visible surface per pixel for each layer?
And if you separate the scene into fine-enough layers to achieve that,
won't you also incur a big overhead?
