Okay, I think I figured that out... There are still a number of problems that 
I haven't been able to solve, but I've checked the code, debug lines and all, 
in.

* Undoing a crop causes a crash -- I guess that there is a problem because the
memento rollback mechanism cannot handle the fact that the new situation has 
fewer tiles than the old situation it wants to restore.

* I cannot seem to move the resulting layers to the origin of the image, i.e.,
crop to a bit in the middle of an image, then all layers should go to 0,0 -- 
but I can call move(0,0) until I see blue in the face, but the layers won't 
move. I don't understand how the move tool works, evidently.

Anyway, once I grasp the solution to these problems, I guess I can easily 
implement the missing clear & paste methods in the tile manager.
