Public bug reported:

enblend/enfuse set the position of the image to the upper left corner of
the the combined images. this is wrong. it should be set the x/y offsets
passed to the -f argument. because of a bug in the blacklisted exif keys
the program would write the x/y position of the first image. even after
fixing the regular expression and setting the position to what was given
in the output file, the programs would still ignore the offsets because
then it would filter out the x/y position from the data read from the
file list and overwrite the already existing position when writing out
the new metadata. the fix is to sanitize the data read from the files to
be blended, read back the old metadata from the blended file, merge it
with the sanitized metadata and then write it back to the file. i'm
attaching the patch to fix this.
