Zoom in to florida, USA and switch to the swedish map. It will come up with exception at:
    public override GSize GetTileMatrixMinXY(int zoom)
    {
        if (extentMatrixMin == null)
        {
            GenerateExtents();
        }
        return extentMatrixMin[zoom];
    }
in SWEREF99_TMProjection.cs
