symdef for sTeX logo name is not handled properly

[kohlhase]

In stc/slides/sTeX/en/sTeX-approach.tex we find

\symdef{sTeX}{\mbox{\raisebox{-.5ex}S\kern-.5ex\TeX}}

and this is transformed to

    <notation cd="sTeX-approach" name="sTeX">
      <prototype>
        <om:OMS cd="sTeX-approach" name="sTeX"/>
      </prototype>
      <rendering>
        <text>TeX</text>
      </rendering>
    </notation>

which is incorrect. This is used in prominent places in the EPC demo book, so it would be nice, if that could be corrected.

If this is difficult, I can just change it to

\symdef{sTeX}{\text{sTeX}}

but I would prefer a real solution.

In the intermediary xml we do have

<text xmlns="http://dlmf.nist.gov/LaTeXML"><text yoffset="-2.15pt">S</text>TeX</text>

The inner <text> disappears in post-processing. If you want to give up presentation information we can just copy and modify \raisebox. Else, just to be nice, we might want to change how LaTeXML treats \TeX (for now it just writes TeX).
