but but, but the raytracer's job is to populate the database. The trace 
data is the render. Everything else is SQL. Image is a query, depthmap 
is a query, normalmap is a query ...

-- depth map as a query, not a render pass
SELECT
   pixel_x,
   pixel_y,
   MIN(t) AS depth  -- closest hit along each ray
FROM bounces
WHERE frame = 42
GROUP BY pixel_x, pixel_y

to take it to the extreme, the render relay should probably be the only 
thing that actually traces rays. Everything else — depth, normals, 
object IDs, albedo — is a material relay or a post-process query.
