    configure: check presence of "gegl:matting-levin" with `gegl --exists`. · 9560a653

    This is a runtime dependency. If absent, we simply won't have access to
    the alternative Matting Levin engine in the foreground selection tool.
    
    If we don't add a test in configure, this may be easily forgotten. I
    created the `gegl --exists` feature specifically for this kind of
    checks, so let's check operation existence.
