This sounds elegant.
One suggestion/question? What if you changed the semantics of the
second argument? Instead of moving based upon the top-left corner, you
move based upon the center of the object? Then you could dispense with
the second argument altogether, because people could just use
margin/border/padding settings to keep the movable within the container?
Just a quick thought, I might not have even thought out all the
ramifications lost in pruning the second argument.
