we've attempted to use OID passes before and run into this exact
problem, motion blur, transparency, etc all got in the way of being
able to use simple per pixel data like this, so we're looking into a
more 'deep' pixel implementation. We've embedded only IDs and use
other 'databases' to store human meaningful data.
