  Regardless of which method is used it's clear that povray must keep
all the necessary information in files (or at the very least in memory)
between renders.

  There could be a few possibilities:

1) An option to tell POV-Ray to write all the necessary information on files.
   Then if you want to re-post-process, you just use the option +C to skip
   the rendering.
   One disadvantage of this is that you have to remember to use the option
   if you want to be able to post-process multiple times.

2) POV-Ray could always write the extra info on files, allowing
   post-processing whenever you want.
   The disadvantage is that it will consume disk space and the user would
   have to manually delete those unneeded files to clean it up.

3) POV-Ray could automatically write the info on files and keep them there
   as long a it's running, and when it's closed, it removes them (unless
   an option is given). This would allow re-post-processing the image as
   many times as necessary as long as POV-Ray is running.
   The disadvantage is that this idea doesn't work with the command-line
   version. Another slight disadvantage is that if the execution of the
   program is ended abruptly, the files will be left there.

4) As 3, but the info is kept in memory until next render.
   Doesn't garbage the disk, but has the same disadvantages.

  Make your pick, or suggest something better.
