Animated tray icon (alternative method)
I think Gajim tray icon that notifies on a new message (direct or mention) would look nicer if animated instead of blinking (displayed/hidden), and I guess that most would agree with me.
Liferea has two ways of indicating on new ATOM/RSS feeds:
Default: When there are no new feeds, systray icon is grayed.
- When there are new feeds, systray icon is colored.
- When there are new feeds, systray icon is colored and a number of unread feeds is displayed on it.
Instead of relying on GIF animation, which does not work with GTK systray, switch between two different icons every 1.5 seconds (or any other period).
