We still load the surface into an StImageContent, but instead of adding the content to an actor we hand out, return the content itself (as GIcon). That means we lose the ability to specify an icon size, but as we get the pixel data from a fixed-size surface anyway, that shouldn't matter much in practice. Not to mention that the function is only used for fallback X11 icons, which are already shit more often than not. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1342
