	Okay, so I've done some work on a simple API for adding icons to the
Notification Area. Its in libegg. But it sucks in its current form:

	* Its currently geared towards "status icons" - that is, an icon that
remains in the notification area while the app is running and the app
switches the icon around as some status changes. It needs an API for an
icon that is added and removed as a certain event occurs ...

	* The API for setting an array of icons and then using a status
identifier to index into the array sucks. Couldn't think of a nicer way
to do it.

	But anyway, its a start - I've appended it below.

	I've only ever had a quick look at the Win32 API for this, but my
interpretation was similar to what Havoc says in #105101. I think the
API below could be implemented in Win32, but I'd be very interested to
hear from someone who actually knows what they're talking about :-)

	As regards this API limiting people on X11, maybe gtk+ on X11 could
also ship something similar to EggTrayIcon (effectively only an
implementation of the protocol). That way people can do their fancy
embedding if they want, but they know they are limiting themselves to
X11 only - in a similar way to GtkPlug/Socket. Hmm, its just occurred to
me that that would mean the widget would sub-class different widgets on
Win32 and X11. Ouch.

Good Luck,
