[Elm_Dnd] Correct drag position when rotation

Summary:
When window is rotated, the drag position is not updated.
It makes dnd cannot find out correct dropable objects.
This patch updates the drag position when window is rotated, so that dnd can find correct dropable objects.
@fix

P/S: This patch is originated from JackDanielZ (Daniel Zaoui). I update it to conform with lastest code.
