Issue #1307 -- Use MathML not images for math

From: Neil Soiffer <NeilS@DesSci.com>

I think the following changes should be made to Test 135:
http://www.w3.org/WAI/GL/WCAG20/tests/test135.html


The "fail" test is text with an image that contains math.

The current test includes all of the words that would be spoken if one read
the expression and are redundent with the image.  I think text should simply
be:
<p>The following image shows the solution to the quadratic equation: </p>


The pass test currently has triple redundancy:  text that includes the words
used to describe the image, the image, and the mathml that should be used in
place of the image.

The image should not be there since that is the point of the test ("Use
MathML not images for math").

The text should be shortened as above to:
<p>The following shows the solution to the quadratic equation: </p>

In this case, a screen reader that comes upon the MathML will say exactly
what is in the text that should be deleted.  Ie, the screen reader will say
something like "begin fraction minus b plus or minus begin square root of b
squared minus four a c end square root over 2 a end fraction" when it comes
to the MathML.
