They have removed some information from their documentation in recent versions. 
As of 4.5, they are only claiming to support the static features of SVG 1.2 Tiny 
in both the rendering and generation:

   http://doc.qt.nokia.com/4.5/qtsvg.html

SVG 1.2 Tiny does not support clipping.

   http://www.w3.org/TR/SVGMobile12/

That's why the bug reports have been closed as "won't fix". They are out of 
scope for the standards they have decided to support.

It might be worthwhile for matplotlib to only use the SVG 1.2 Tiny standard for 
greater compatibility. Tiny is much easier to implement, so I suspect there are 
now more Tiny renderers now than there are Full renderers.
