- *   
- *   mxVmlCanvas2DImage.apply(this, arguments);
- * };
- * (end)
- * 
- * To disable anti-aliasing in the output, use the following code.
- * 
- * (code)
- * document.createStyleSheet().cssText = mxClient.VML_PREFIX + '\\:*{antialias:false;)}';
- * (end)
- * 
- * A description of the public API is available in <mxXmlCanvas2D>. Note that
- * there is a known issue in VML where gradients are painted using the outer
- * bounding box of rotated shapes, not the actual bounds of the shape. See
- * also <text> for plain text label restrictions in shapes for VML.
