    retro-runner: Use savestate aspect ratio for pixbufs
    
    Use Retro.pixbuf_set_aspect_ratio() before sending the pxibuf to retro-gtk.
    This ensures that the pixbuf is displayed with correct aspect ratio.
    
    If no aspect ratio is present, do nothing, falling back to the previous
    behavior.
