-    - Similar to dnd, create a selection object for a device to offer
-      selection data:
-

-	 - selection.offer(type)

-    - Notes: no window owner, which seems to be mostly there as a way
-      to identify the client and to allow None (instead of a release
-      request).  Possibly also to make the selection go away
-      automatically when the window with the contents go away, or
-      possibly as a way for the source to distinguish between multiple
-      selections.  Toolkits generally just create a dummy-toplevel for
