We are also starting to see some graphical editing applications. In an effort to satisfy a potential, future, demand to have graphical editing everywhere (it could happen), I created a Javascript component called RichDraw.

I made some changes to the IESVG behavior. I am trying to get better feature coverage without making the rendering too slow. I have been testing the code using some SVG images from different places, trying to figure out what parts of SVG seem to be more important than others. Recents chanegs include:

The behavior will walk the SVG element structure and attempt to convert to appropriate VML elements. It’s far from complete, but it does a decent job. Supported features include:
