Hmm, mutt doesnt seem to like me today, because yet again I have replied to someone, and it replied to them and not the list. =| What I replied is as follows: Hrm, well, whatever works, you know? I thought 16-bit per channel would have been enough, but if you wanna do 32-bit per channel, go ahead. (It should render beutiful images up high like that) All we need is someone that would want to add it.
