Exporting to mapnik xml with custom image and font paths

[horacer]

Sorry, I've got another one ;)

I just created a xml file out of my project, to use it outside of the magnacarto project dir. Therefore I was using magnacarto bin with -relpaths, -font-dir, -image-dir to reflect my setup. But despite those flags beeing set, it doesn't make any difference. All the paths within the xml are still an absolute path to the magnacarto project dir.

Any thoughts or comments on this one?
