[WWcvs] webwork2: Bring jsMath up to version 3.5.

[dpvc v. a. <we...@ma...>]

Log Message:
-----------
Bring jsMath up to version 3.5.  Changes include:

* Fixed a problem with the boldsymbol extension where it could leave the
fonts set to the bold fonts, so that all the rest of the mathematics on the
page would be in bold.  (This would occur if a jsMath auxiliary file had to
be autoloaded by the \boldsymbol command.)

* Fixed a timing problem with easy/load.js when autoloading and tex2math
are both used (the default) that could cause some internal routines to run
in the wrong order.

* Fixed a problem in detecting a font size change in MSIE when the font
used at one location on the page is only slightly smaller or larger than
that used at the previous location.

* Added ability for extra fonts to specify how they are handled in
symbols-only image mode.  This is used by the cmmib10 font to specify that
the italic letters should be handled by bold italic letters in the serif
font rather than by images, which was the old behaviour.  You will need to
replace the jsMath/fonts/cmmib10/def.js file with the new one to take
advantage of this.

* Added a new autobold extension that allows jsMath to detect the presence
of a <B>...</B> tags (or CSS that sets font-weight:bold) surrounding the
mathematics and automatically apply \boldsymbol to the mathematics.  Since
this requires the extra cmmib10 and cmmsy10 fonts, this is an extension
that you must activate yourself.  See the autobold documentation for
details

* Implemented the \verb command for entering verbatim material.  See the
verb extension documentation for details.

* Added aligned and gathered environments to the AMSmath plugin.

* Added equation and equation* environments.  (Since tex2math now processes
LaTeX environments within the text of the page, it makes more sense to have
these defined.)

* Fixed a problem with \newcommand where it would reject
control-sequence names that included upper-case letters.

* Fixed a problem with the \font command where the control sequence would
be lost when the font was loaded (if it wasn't already loaded when the
\font command was issued).

* Fixed a timing bug with easy/load.js when there are files specified in
the loadFiles array.  The bug only occurred with the Opera browser.

* Worked around a problem with Opera where the autoload plugin could hang
when trying to load the jsMath.js file.

* Worked around a spacing problem in IE7 where some elements in an array or
fraction could be misaligned.

* Worked around a problem in IE7 where accented characters could disappear
under some circumstances (particularly when they appear by themselves).

* Fixed a problem with Firefox3 where the control panel would not open.

* Firefox3's new single-origin policy restricts access to file outside the
currect directory when local files (i.e., file: URL's) are used.  JsMath
now uses the new window.postMessage() facilty to work around this.  If you
use window.postMessage() yourself you should be aware that jsMath is also
using window messages, and so you should be careful to properly identify
your own messages so as not to confuse them with the ones used by jsMath.
All messages used by jsMath will begin with jsMLD:, jsMCP:, or jsMAL: so
you can filter these out of our own message-processing code.

* Disabled the BaKoMa font processing in Firefox3 since jsMath no longer
works properly with those fonts in Firefox3.
