Subject: Tweak the math-as-LaTeX output, including the correct tags for jsMath.
X-Git-Tag: 2.0.0~2917
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=c036ecb649c275bd55f022f6d20d778895148951;p=features.git

Tweak the math-as-LaTeX output, including the correct tags for jsMath.
We don't yet write info to load the jsMath files, though.
