Ah, I didn't realize getTransferData() was called as soon as
a valid drop target is identified (but before the drop). I suppose
the targets need that if they display something about the
nature of the items to be dropped on mouse-over. I don't see
any way to tell the difference between a mouse-over and
actual drop. The methods in the call stack are identical for
both, and the line numbers are mostly unknown.
