Exporting fonts as outlines in SVG (was: \markup \sans ... does not always give sans-serif output in svgs in 2.19.36)

[Urs Liska]

Slightly OT but still related:
would it be possible to (optionally) export text fonts as outlines in
the SVG?
As it is SVG is only properly displayed if the fonts are installed on
the viewer's machine - something you can't expect when producing for web
display (which should be a major target for the SVG backend).
