# From the Microsoft documentation:
#
# Any time the "Maker Note" is relocated by Windows, the Exif MakerNote
# tag (37500) is updated automatically to reference the new location. In
# addition, Windows records the offset (or difference) between the old and
# new locations in the Exif OffsetSchema tag (59933). If the "Maker Note"
# contains relative references, the developer can add the value in
# OffsetSchema to the original references to find the correct information.
#
# My recommendation is for other developers to ignore this tag because the
# information it contains is unreliable. It will be wrong if the image has
# been subsequently edited by another application that doesn't recognize the
# new Microsoft tag.
#
# The new tag unfortunately only gives the difference between the new maker
# note offset and the original offset. Instead, it should have been designed
# to store the original offset. The new offset may change if the image is
# edited, which will invalidate the tag as currently written. If instead the
# original offset had been stored, the new difference could be easily
# calculated because the new maker note offset is known.
#
# I exchanged emails with a Microsoft technical representative, pointing out
# this problem shortly after they released the update (Feb 2007), but so far
# they have taken no steps to address this.
