    media-keys: Copy get_image_name_for_volume() from gsd-osd-window.c
    
    Just as we now refer key grabbing to the shell, we will do the same
    for OSD popups. Determining the correct volume icon is something
    we'll still need to do, while the rest of GsdOsdWindow will become
    obsolete and removed, so copy the function over.
