Does this mean any further questions will be ignored ? I hope, not ;-)

First to your question : if I understand correctly the proposed API is to 
let GTK work after a model called "delayed rendering" in the windoze world. 
That is not simply create the whole clipboard content on ctrl-C but just 
advertize the ability to create the content (in some formats) on request.
When the application ends and there still is some data 'advertised' in the 
clipboard the users gets asked if it should be rendered now or dropped. If 
it should be rendered it is triggered by a call to 
gtk_clipboard_wait_for_exit_cleanup()

If my understanding is right, it certainly should be implementable on 
win32, although the current code in gdk/win32 does not make use of delayed 
rendering -  following the comment cause of implementation problems - maybe 
related to the differences in clipboard owner models (already tried to get 
some comment from X experts in my previous mail on the subject, but 
apparently failed ;)

Now for my questions : all this dealing with GTK Clipboard improveents is 
still restricted to plain text, right ?
Wouldn't it be feasible to extend the API while on it to at least have 
something like QClipboard::setImage(), i.e. gtk_clipboard_set_image() and 
gtk_clipboard_get_image(). Or is what QT does so far away from a standard, 
that it shouldn't be considered for GTK ?

Oh, and while on the subject of IMO real clipboard improments, could 
something  be done to also support vector data ? Maybe stuff in SVG from 
the cross platform application [GIMP and Dia spring to my mind, but there 
are obviously more] and silently convert it to WMF/EMF on demand within the 
gdk/win32 backend - and do what ever is appropriate for X11 ?

Thanks,
