\brief This is the function that does all of the SVG saves in
Inkscape. It detects whether it should do a Inkscape
namespace save internally.
\param mod Extension to use.
\param doc Document to save.
\param uri The filename to save the file to.
This function first checks it's parameters, and makes sure that
we're getting good data. It also checks the module ID of the
incoming module to figure out if this is save should include
the Inkscape namespace stuff or not. The result of that comparison
is stored in the spns variable.
If there is not to be Inkscape name spaces a new document is created
without. (I think, I'm not sure on this code)
All of the internally referenced imageins are also set to relative
paths in the file. And the file is saved.
This really needs to be fleshed out more, but I don't quite understand
all of this code. I just stole it.
