ChromiumWebBrowser.StartDragging Method

Called when the user starts dragging content in the web view. OS APIs that run a system message loop may be used within the StartDragging call. Don't call any of IBrowserHost::DragSource*Ended* methods after returning false. Call IBrowserHost.DragSourceEndedAt and DragSourceSystemDragEnded either synchronously or asynchronously to inform the web view that the drag operation has ended.
