* Pulled in MathJax 1.1 (minus the 112 megabytes of PNG "fonts") * Pulled in some of <https://en.wikipedia.org/wiki/User:Nageh/mathJax> bits for initialization This doesn't currently override PNG images, but does replace the text-form if you configure it.

*
|
|
* MathJax/extensions/TeX/noErrors.js
|
|
*
|
|
* Prevents the TeX error messages from being displayed and shows the
|
|
* original TeX code instead. You can configure whether the dollar signs
|
|
* are shown or not for in-line math, and whether to put all the TeX on
|
|
* one line or use multiple-lines.
|
|
*
|
|
* To configure this extension, use
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* TeX: {
|
|
* noErrors: {
|
|
* inlineDelimiters: ["",""], // or ["$","$"] or ["\\(","\\)"]
|
|
* multiLine: true, // false for TeX on all one line
|
|
* style: {
|
|
* "font-family": "serif",
|
|
* "font-size": "80%",
|
|
* "color": "black",
|
|
* "border": "1px solid"
|
|
* // add any additional CSS styles that you want
|
|
* // (be sure there is no extra comma at the end of the last item)
|
|
* }
|
|
* }
|
|
* }
|
|
* });
|
|
*
|
|
* Display-style math is always shown in multi-line format, and without
|
|
* delimiters, as it will already be set off in its own centered
|
|
* paragraph, like standard display mathematics.
|
|
*
|
|
* The default settings place the invalid TeX in a multi-line box with a
|
|
* black border. If you want it to look as though the TeX is just part of
|
|
* the paragraph, use
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* TeX: {
|
|
* noErrors: {
|
|
* inlineDelimiters: ["$","$"], // or ["",""] or ["\\(","\\)"]
|
|
* multiLine: false,
|
|
* style: {
|
|
* "font-size": "normal",
|
|
* "border": ""
|
|
* }
|
|
* }
|
|
* }
|
|
* });
|
|
*
|
|
* You may also wish to set the font family, as the default is "serif"
