    gegl: in init be more precise about setting mipmap-rendering
    
    Fixing issue #239, as it was if GEGL_MIPMAP_RENDERING was set at all it
    would be enabled, we now behave more like the other environment
    variables and allow turning it off (which for now also continues being
    the default).
