Patch to detach image data before replacing the image data in rotate function

Attached patch adds the call to detach just before the old data is deleted.

This is not the most efficient way, as the image data is copied (if necessary)
in the detach function, and then immediately discarded after the return from
detach.

There is also the chance that between the call to detach and the data being
replaced that another thread could make a copy of the Dimg and have a pointer
to the deleted data .
