    • dragImage

      Initiates Drag and Drop for the given image with the list of mouse events.

    • translateRectToDropDestination

      public static void translateRectToDropDestination(RMRect dragShapeBounds, RMPoint overShapePt)
      Set the origin of the rect to match the image being dragged around.

      Right now this is used to handle the fact that the position of the drag image in relationship to the cursor is different depending on whether the image dragging is being done by the system or by us. It can also be used at some point if we want to make the image dragged from where it was clicked on initially, instead of in the middle (in the system drag case).
