    Revert "nautilus-file.c: Add transparent padding to thumbnails"
    
    This reverts commit 26d33d74f468a8ab10b4a1c3c8aa66b66205e112.
    
    It was a hack to fix an issue with the way GTK 3 renders GEmblemedIcon.
    
    But GTK4 has dropped support for rendering GEmblemedIcon[0], so we
    aren't going to have any need for this hack going forward.
    
    Also, the new icon view now draws shadows around thumbnails. But due
    to this hack, the shadow would always go around the invisible square.
