SVG is great, the only feature I miss is word-wrapping. Does any of these libraries have automatic support for breaking long strings in paragraphs?

I have done myself something similar [1] for PHP's Zend\Pdf library, calculating string lengths and breaking lines.

Also, it is worth mentioning Dojo's GFX library.
