    static Texture2D GetIcon()
    {
        if (s_Icon == null)
        {
            s_Icon = new Texture2D(8, 8);
            for (var y = 0; y < s_Icon.height; ++y)
            {
                for (var x = 0; x < s_Icon.width; ++x)
                {
                    var border = y == 0 || y == s_Icon.height - 1 || x == 0 || x == s_Icon.width - 1;
                    var color = border ? Color.white : Color.red;
                    s_Icon.SetPixel(x, y, color);

            }
            s_Icon.Apply();
        }
        return s_Icon;
    }

    public void DrawOverlay(string assetPath, IconOverlayType type, Rect rect)
    {

        var icon = GetIcon();
