Subject: [PATCH] iconfactory: cache/invalidate pixbufs according to the effect

The state of the widget is not enough now to cache the pixbuf - we also
have to take into consideration the image effect itself, since the state
on the actual GtkStyleContext we use might not change, e.g. because the
change was on a parent context.
