Re: [Bug 90166] Add a way to specify units (in SVG output)

If I understand that right, "percent" is not allowed in the style attribute.

Also it seems like the default is "user". By default I mean what svg
does if you don't specify the unit at all. If cairo has been forcing
that value to pt then I think Cairo is wrong.
