The image format (whatever could it be with +F...) in 3.7 is generated
only at the very end of the rendering process.

Nevertheless, if you use the intermediate file storage (which slow down
the render process if it is quick), which is used for big resolution (as
it is triggered by default for 128 MB of raw buffer)
( see http://wiki.povray.org/content/Documentation:Reference_Section_1
+MI option), you could get some data. I guess I would have to document
that file (fixing it forever... )

You could instead use a +D switch to open a preview window. That's
assume of course that the DISPLAY setting of X11 has been set for the
relevant systems (unix-like).
