[Octave-bug-tracker] [bug #43827] print svg with incorrect font baseline

[Andreas Weber]

Follow-up Comment #3, bug #43827 (project octave):

The SVG attribute in question is "baseline-shift"
http://www.w3.org/TR/SVG11/text.html#BaselineShiftProperty

The svg generated by gl2ps looks fine for me. It uses font-size="10" and
baseline-shift="-10" to draw the xlabels which should show text below the
box.

I've found a bugreport because baseline-shift isn't implemented in Firefox:
https://bugzilla.mozilla.org/show_bug.cgi?id=308338

I created a testimage

<?xml version="1.0"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
  "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";>

<svg version="1.1" xmlns="http://www.w3.org/2000/svg";>
  <text x="10" y="40" style="font-size:26px">
    (a+b)<tspan style="baseline-shift:super;font-size:18px">2</tspan>
  </text>
  <text x="10" y="80" style="font-size:26px">
   c<tspan style="baseline-shift:sub;font-size:18px">11</tspan>
  </text>
  <text x="10" y="120" style="font-size:26px">
    K<tspan style="baseline-shift:-20;font-size:18px">i=0</tspan>
  </text>
</svg>


Only Inkscape renders correct here, LibreOffice, Gimp and Iceweasel fail
