Comment 4 for bug 950264

But we do ship a default theme with wingpanel that sets the text color already. The merge I've proposed just adds GtkImage to the list of classes.

There is absolutely no code whatsoever in any theme that deals with wingpanel. If you think we should move this theming into eGTK and no longer supply a theme that's fine, but that means we need to add the class names to wingpanel so that this is possible. And it guarantees breakage in other themes because no other theme cares about wingpanel at all.

Ambiance and Radiance will never be a perfect fit for Pantheon because they are Unity themes. That is just the reality of it.
