But it still does not support copying image via Clipboard, or di I miss 
this? I should have been more clear with what I would like to be able to do :

- copy images to clipboard via cross-platform gtk/gdk code (could replace 
my winclipboard plug-in delivered with Gimp)

- copy vector data to Clipboard (one of the major drawbacks of Dia - at 
least on windoze - is it's diability to just copy some stuff and paste it 
into say word)

Yeah, obviously it is possible on win32 - even without OLE. The 
Clipboard  API works with shared memory (i.e. GlobalAlloc see 
gimp/plug-ins/common/winclipboard.c). But on X it appears to be either so 
complicated or so unusual to do/want this, that nobody bothers to implement 
it ...

Hopefuly I'm wrong,
