DefaultRenderHandlerStartDragging Method

Called when the user starts dragging content in the web view. Contextual information about the dragged content is supplied by dragData. OS APIs that run a system message loop may be used within the StartDragging call. Don't call any of the IBrowserHost.DragSource*Ended* methods after returning false. 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.
