Public methodGetViewRect
Called to retrieve the view rectangle which is relative to screen coordinates. This method must always provide a non-empty rectangle.

Return true to handle the drag operation. Call DragSourceEndedAt(Int32, Int32, DragOperationsMask) and DragSourceSystemDragEnded either synchronously or asynchronously to inform the web view that the drag operation has ended.
