        svgString - The SVG string.
        width - Scale to width in logical pixels, zero or negative for no scaling of the width. If non-zero, the height must also be non-zero, otherwise no width scaling is assumed.
        height - Scale to height in logical pixels, zero or negative for no scaling of the height. If non-zero, the width must also be non-zero, otherwise no height scaling is assumed.
        Throws:
        java.lang.NullPointerException - If the svgString is null.
        java.io.IOException - For read errors.
