Drag and Drop

Native drag and drop can be enabled per-window. Simply set the EnableDragAndDrop window config option to true and the window will allow files to be dragged onto it. When this happens, the events.FilesDropped event will be emitted. The filenames can then be retrieved from the WindowEvent.Context() using the DroppedFiles() method. This returns a slice of strings containing the filenames.
