[Spice-devel] [PATCH] vd_agent: support clipboard/selection-owner model

[Arnon Gilboa]

Windows is not "waiting" for me to render. It just closes the clipboard. 
If we do nothing on receiving WM_RENDERALLFORMATS, the clipboard is 
actually kept empty, because using the delayed-rendering-way we have 
already called EmptyClipboard() in handle_clipboard_grab(). I think 
doing nothing is the right thing here.
