I meant the thumbnail, sorry.

My general opinion about this is that this looks like the rare
case where a prefs setting makes sense:

There seem to be two classes of desktop enviromnents: those which show
a panel/taskbar/foo icon per window, and these use the thumbnail; and
those which show an icon per application, and these use the icon.

Then there is two types of users: those who find the thumbnail weird,
and those who find it helpful.

I think a simple "Use Image Thumbnail as Window Icon" boolean toggle
should IMO work just fine, but we definitely should

1. render the thumbnail always as a square (padded with transparency)
   because at least GNOME distorts the thumbnail to be a square.

2. overlay a wilber icon if we render a thumbnail to make the window
   icon recognizable as "GIMP Window".
