disable backface culling for Freestyle?

Hey how can I disable backface culling for freestyle to also render lines behind faces?

You might say just use wireframe rendering, but I need to use this with Freestyle because I need to export the lines it geenrates as SVG files and Freestyle doesnt support wireframe mode.

Liero’s render svg script?

Quick test:

I use this plugin because it allows sequence export and supports all the options freestyle does. http://sourceforge.net/projects/dxfwriter/

Perhaps setting the “Visibility” mode to “Qi range” in Freestyle is the way to go?
