-// Some notes about drag and drop handling:
-// Windows drag and drop goes through a system call to doDragDrop. At that
-// point, program control is given to Windows which then periodically makes
-// callbacks into the webview. This won't work for layout tests, so instead,
-// we queue up all the mouse move and mouse up events. When the test tries to
-// start a drag (by calling EvenSendingController::doDragDrop), we take the
-// events in the queue and replay them.
-// The behavior of queuing events and replaying them can be disabled by a
-// layout test by setting eventSender.dragMode to false.
