[Vv] Bug when saving an image that has an associated transformation matrix

[Simon Rit]

True. So far, we have chosen to save them separate, the data on the
one hand and the transform matrix on the other (you can back it up in
a text file via the manual registration tool which will be
automatically opened if named with the default name). I am willing to
implement the backup of the matrix at the same time but I would need
an agreement. I don't have a strong opinion but does someone object?
Note that one would always be able to change matrix to identity
(right-click in the information panel).
