/* FileWellView is a View subclass that conforms to the
NXDraggingSource protocol. It provides a visual representation
of the three most common types of file selections one
sees in a browser -- document, folder, and multiple.
As an NXDraggingSource, one can drag the image over
NXDraggingDestinations that accept the NXFilenamePboardType
of data we provide. We require a delegate that implements our
provideSrcData: delegate method. We provide NX_DragOperationGeneric,
NX_DragOperationCopy, and NX_DragOperationLink operations. */
