Remove client-side overlay handling, use the X-server v4l plugin
for that. Nicer overlay, less code. Also make the plugin
compileable without X (but then without overlay, obviously).
Makes xwindowlistener obsolete, should we remove that?

Remove client-side overlay handling, use the X-server v4l plugin
for that. Nicer overlay, less code. Also make the plugin
compileable without X (but then without overlay, obviously).
Makes xwindowlistener obsolete, should we remove that?
