Subject: [PATCH] Call MATML.Parse.prototype directly rather than make a
 special flag for preprocessing.  Use MATHML variable rather than full
 reference.

+ *  Presentation MathML for processing by MathJax.  The transform is
+ *  performed in a pre-filter for the MathML input jax, so that the
+ *  Show Math As menu will still show the Original MathML as Content MathML,
+ *  but the Presentation MathML can be obtained from the main MathML menu.
