Unfortunately, when writing an animation to anything other than stdout, it
insists to append the frame number to the file name. It is therefore not
possible to avoid having one directory entry per frame, either all at once
or on demand. I prefer to have them on demand.

The easiest solution is probably to make them a symlink to /dev/stdout, if
stdout is not a socket. At least, POV-Ray does not write anything to stdout
unless ordered to.
