[Cin] Images sequence

Sorry to insist, but I think DPX support is very important.

It would take more testing by other users. As I wrote in a previous
message, some versions work for me, and even in Arch, DPX and PNG used
to work for me (not anymore, now).

@IgorBeg
Please, can you test the rendering of a sequence of images (it only
takes a few seconds), since you normally use Ubuntu 16?

FFmpeg creates the images with a command (muxer) that implies %05d in
the name and then, thanks to the image2 command (demuxer), it reads
them (without the need to create a TOC file) and creates the video. It
occurs to me that CinGG presets create the images via %05d and then,
instead of being read by image2, the TOC file (not the video file!) is
created and can be imported into CinGG (or other program). Perhaps a
version of "imagelist.sh" is implemented? In short, the difference
between ffmpeg and CinGG is the creation of the TOC file.

I remember that my hypothesis about the problem is the management of
absolute/relative paths, since the TOC is created and works: only the
links are missing. Is it possible to trace a patch that has touched
the paths? If not, I'll say again that it's better to delete these
presets and the related entries in the manual altogether.
