SvgRenderer

Implement IGraphicsProvider and ISvgRenderer.
Has Graphics.

public static ISvgRenderer FromImage(Image image)

    g.PixelOffsetMode = PixelOffsetMode.Half;
    g.CompositingQuality = CompositingQuality.HighQuality; // for compositing.
    // for text.

}

g.SmoothingMode = SmoothingMode.AntiAlias;
// -> completely horizontal and one width lines are blurred...

GraphicsPath

GetBounds()
- GetBounds() is readonly. (returns Bounds copied.)
- Bounds is only draw area. (Whitespace character etc. at both ends are not included.)
AddPath()
- AddPath() cannot set empty GraphicsPath(PointCount is zero). (ArgumentException is thrown.)
