Fail more gracefully when window state changes during drags
In particular, if a new window was created out from under the drag,
the drag-move event dispatch logic would wind up blithly assuming
that it would find a valid touch-dispatchable window under the
finger. When this was untrue, it would NPE, but the NPE was caught
and discarded safely by higher-level guard code.
With this change, we now avoid the NPE entirely and report the
spurious condition as part of the debugging log stream.
(Also add the local-state object to DragEvent.toString()'s output.)
