svg: text to paths

[uakci]

So the conversion, which went like this:

for f in **/*.svg; do
  inkscape --export-type=svg --export-overwrite --export-text-to-path "$f"
done

seems to have gone through without issue. One minor thing I've spotted is that there is some extra spacing after italic text, like here. But that's all I can do without resorting to possible manual intervention for each SVG, or futzing with the raw XML.
