Right. To clarify, I meant that we'd either keep the existing dialog and 
use it as a "wizard" to create additional filters doing the same 
operations that are currently "baked", or else we would indeed only 
create debayer + wb. Either would be OK with me, though I lean a bit 
toward "wizard" mode.

Ok, I guess libkdcraw needs work then :-). (Ah... *dcraw* can provide 
the raw, pre-bayer data, right? And libkdcraw is a dcraw wrapper, yes?)
