As explained in my other post dividing the pixel colors into the different
contributing parts (i.e. reflected, refracted and direct, possibly split
into different parts) would be useful for post processing.

I think you are right to point out the memory problems.  This was a major
problem already in the original post processing patch - post processed
focal blur on a print size render was quite difficult.  Maybe it could be
avoided to have the data for the whole image in memory.  For just writing
the data to a file for processing in external programs this should not be
difficult but for internal operations this is of course quite tricky.
