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. | |||
