After having some problems with text in SVG's I wondered if it might have something to do with the kerning/spacing.
Can someone checK that the render backend is correctly reading these:
https://www.w3.org/TR/SVG11/text.html#TSpanElementXAttribute
https://www.w3.org/TR/SVG11/text.html#TSpanElementDXAttribute
in respect of text and tspan.
