So far, rare render errors caused by blips in the network or the mathoid
service produce a big red warning in the page, and cause a tracking
category to be added. The rendered content along with the error message
is cached normally, which means that temporary errors are persisted
indefinitely.
As a consequence, editors need to periodically perform null edits to
remove temporary render errors from caches. T136812 documents a history
of this.
This patch aims to improve error handling through two changes:
1) Limit caching of rendered content to 10 minutes. As a consequence,
temporary render errors should clear themselves up fairly quickly,
eliminating the need for manual follow-up. The 10 minute timeout was
chose as a compromise between relatively timely cleanup, and limited
load from re-renders after math trouble.
2) Track render errors in a dedicated category. This avoids mixing
syntax errors with temporary render errors, which should make cleanup
efforts a lot simpler.

1) Because enabling native MathML now requires special configuration steps
from the users, they can as well just check their math font setup. Hence we
remove the Web font fallback.
2) We then can actually just remove ext.math.desktop.css since no specific
style is necessary any more on desktop.
3) We also no longer need to add the Web font to the list of font-family on
the <math> element. We actually just remove the whole font-family rule so
that it is up to web engines developers & users to decide the best math font
to use (e.g. via the "Fonts for mathematics" option in the font preference
menu of Firefox).

The signature of the Hook function is not respected.
Thus parameters need to be passed by reference explicitly.
For syntax validation to pass, this requires
mediawiki-codesniffer to 0.6.0

Most info-level log entries are actually debug messages, which should
not end up in the production log by default, so adjust them.
Only the Mathoid-powered TeX check fail has been promoted to info so
that we can quickly identify such requests from pages.

termination at the root with the main intend, and less indention.

of abstraction (via the constructor).
* White spacing.
* require_once is not a function.

The type text allows text with maximum length of 64k only. Since the
MathML generated by LaTeXML is quite verbose this is too small for
some equations used at Wikipedia.

While the combination of all redering modes, might
be useful for some power users it will confuse the
average user and makes bug reporting harder.
Therefore, source rendering on the server side is
used when MathJax is enabled on the client side.

When MathPlayer is installed, we show the MathML instead of the SVG fallback.
This will in particular allow the sync highlighting feature of MathPlayer.
This also introduces a module ext.math.js that could be used to do some

Currently the method render always returns
a html string that can be a string that
represents the correct result or a rendered
error message.
This change splits rendering and
fetching of the HTML output.
This simplifies the logic of the rendering
and caching mechanism.
Now the render method returns a boolean that
indicates if the rendering was sucessful or
not.
Step 2/2
Warning: Errors in this change might affect
caching logic and squid caches.

Currently the PNG and the LaTeXML rendering mode
use a common table in the database. If both rendering
modes are allowed in a wiki simultaneously this causes
problems, because the fields are continuously overwritten.
This change creates the new database table defined in step 1.

To adjust the selectable math rendering modes in user preferences $wgMathValidModes
is introduced.
* $wgUseLaTeXML becomes unnecessary use $wgMathValidModes[] = MW_MATH_LATEXML;
to enable the LaTeXML rendering mode
* add $wgMathValidModes[] = MW_MATH_MATHJAX; to enable MathJax
Currently, MathJax is bound to the MW_MATH_SOURCE rendering mode.
This change makes the base mode user configurable.
That means before MathJax is loaded the png fallback image could
be displayed.
ATTENTION: This change modifies global variables as follows:
* MW_MATH_MATHJAX is deprecated.
