+ *
+ *  MathJax/extensions/TeX/bbox.js
+ *  
+ *  This file implements the \bbox macro, which creates an box that
+ *  can be styled (for background colors, and so on).  You can include
+ *  an optional dimension that tells how much extra padding to include
+ *  around the bounding box for the mathematics, or a color specification 
+ *  for the background color to use, or both.  E.g.,
+ *  
+ *    \bbox[2pt]{x+y}        %  an invisible box around x+y with 2pt of extra space
+ *    \bbox[green]{x+y}      %  a green box around x+y
+ *    \bbox[green,2pt]{x+y}  %  a green box with 2pt of extra space
+ *
+ *  You can also specify style attributes, for example
+ *  
+ *    \bbox[red,border:3px solid blue,5px]{x+y}
+ *  
+ *  would give a red background with a 3px solid blue border that has 5px
+ *  of padding between the border and the mathematics.  Note that not all
+ *  output formats support the style specifications.  In particular, the
+ *  NativeMML output depends on the browser to render the attributes, and
+ *  not all MathML renderers will honor them (e.g., MathPlayer2 doesn't
+ *  render border styles).
+ *  
+ *  This file will be loaded automatically when \bbox is first used.
