/**
*
* Class: mxVmlCanvas2D
*
* Implements a canvas to be used for rendering VML. Here is an example of implementing a
* fallback for SVG images which are not supported in VML-based browsers.
*
* (code)
* var mxVmlCanvas2DImage = mxVmlCanvas2D.prototype.image;
* mxVmlCanvas2D.prototype.image = function(x, y, w, h, src, aspect, flipH, flipV)
* {
* if (src.substring(src.length - 4, src.length) == '.svg')
* {
* src = 'http://www.jgraph.com/images/mxgraph.gif';
* }
*
* 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.
