<tf> A 3x3 transformation matrix specified by 6 values
(child elements <a>, ..., <f>) See
(child elements <m n="0">, ..., <m n="5"> which equal to a,
...,f used in the SVG standard) See
http://www.w3.org/TR/SVG/coords.html#TransformMatrixDefined
for details.
You can also use shortcuts and use an alternative to
specifying six values:
- Translation: <tx>, <ty> (ty, ty default to 0)
- Totation: <rot>
- Scale: <sx>, <sy> (sx is required, sy defaults to sx)
- Translation: <t n="0">, <t n="1"> (both default to 0)
- Rotation: <rot>
- Scale: <s n="0">, <s n="1"> (s[0] is required, s[1]
defaults to s[0])
<alginment type="string"> Text alignment (default: "left-baseline") One of:
"left-top"
