There are three options for math markup that depends on the editor's math preference settings.  These settings
are at [[Special:Preferences#mw-prefsection-rendering]] and are
PNG images
TeX source
MathML with SVG or PNG fallback
All three are heavy with html and css which don't belong in the metadata.
This function gets the rendered form of an equation according to the editor's preference.  It then searches the
rendering for the text equivalent of the rendered equation and replaces the rendering with that.
