Is an OnStartDrag event dispatcher.
DoStartDrag calls any event handler attached to the OnStartDrag event. When creating a component that descends from TControl, override DoStartDrag to provide other responses in addition to the inherited event-handler call when the user starts a drag-and-drop operation.
