I got a tip that it works if one sets xsetwmnormalhints() min_width, 
max_width, min_height and max_height to 16.
Further tests showed that actually min_width or min_height must be > 1 in 
order to show the tray icon. Is this intended?

Also again the question:
does Xfce support balloon messages
https://specifications.freedesktop.org/systemtray-spec/0.1/ar01s07.html
?

Thanks, Martin
