* extensions/boldsymbol.js
*
* Part of the jsMath package for mathematics on the web.
*
* This file implements the \boldsymbol macro. You can activate it
* by calling
*
* jsMath.Extension.Macro('boldsymbol');
*
* which will cause the extension to be loaded only when it is
* needed, or you can force it to be loaded via
*
* jsMath.Extension.Require('boldsymbol');
*
* once jsMath.js has been loaded.
*
* Note that you will need to install the cmmib10 and cmbsy10 fonts
* that are available from the jsMath extra font page at
*
* http://www.math.union.edu/locate/jsMath/download/extra-fonts/
*
* to make this work in image mode. Note that there is no unicode
* fallback for these fonts at the moment.
