<li>magick/command.c (TransmogrifyImage): Complete re-write of

New version moves an existing writable file to a backup file with
tilde (<cite>~</cite>) added to end of file name, writes to the final output
file name, and removes the backup file on success. The new
approach satisfies formats which embed the output name in the file
(e.g. the DPX format) and still works when the output file exists
and is writeable, but is in non-writeable directory. The previous
approach would fail if the output file exists and is writable, but
the directory is not writeable.</li>

mp.film.type, and mp.perfs.offset were being truncated!</li>
