Currently two post request and one get request is sent
for each formula.
This change gets rid of the second post request.

* Do not contact RESTbase in texvc rendering mode and
use the well established tex checking that is already build
into texvc.
* Do not use RESTbase in LaTeXML mode.
Background:
In I1982612e8c6a356e3dbdf447724ac82e5968cc77 RESTbased replaced
texvccheck that was a derivate of texvc designed for people
that wanted to use secure MathML rendering using mathoid.
The integration of mathoid to restbase made this feature obsolete.
However, texvccheck was not only used to check the latex input
that was sent to mathoid, but also the string which was sent to texvc.
Since texvc has already build in tex checking this is not
required and does not improve security.
Finally, users updating from old versions of the math extension
(prior to 2014) that do not have textexvccheck installed,
do not need to compile the texvccheck binary after this change.
PS5: Also treats the case where VisualEditor is not installed.

* Currently the Math extension stores the rendering result from restbase
in the database.
* This creates unnecessary write operations on the database
Change-Id: I5f07474fbf8017e39e94ac2b17676db1c3e92e72
* For tex input, the only form of Math input that
is accepted on WMF wikis, we retrieve MathML and SVG
image from Restbase without using the database cache.

Redo Ibf6bdbd4ea36b4905445d5878f32f7e0b2bc8bac, which was
reverted by I029328849f05ec2afcabf38d2b79b337cb54cbd5.
In addition this patch simplifies the tex sent to the mathoid
server. Instead of {\displaystyle {\textstyle ... } } only
{\textstyle is sent (which overwrites \displaystyle anyway).

The style information for the fallback image is quite sophisticated
and should not be changed.

* MathDebug was intended to provide advanced debugging functionality
for the math extension. However, the interesting debugging and
logging feature never made it from the debug branch to the master.
* The current debug functionality is mostly useless. Only some values
are written to memory and never used thereafter.
* This change moves the existing functionality to the MathSearch
extension and introduced the required hook for that.
Details:
* $wgMathDebug is removed
* A new Hook MathRenderingResultRetrieved is created
* The math rendering object is printed to the svg error
page if wgDebugComments is active (instead of wgMathDebug)

In some cases the SVG property of the mathoid JSON result
seems to be empty.
In that case we ignore the SVG rendering.

MathMathML::renderingRequired called the getSvg
function in MathLaTeXML that caused an automatic
rerendering of the SVG image if it was not cached.
That this rendering is triggered from the function
renderingRequired is contra intutive and should be
avoided.

* Handle-error-first approach for consistent function body
termination at the root with the main intend, and less indention.
* __DIR__ instead of dirname( __FILE__ )
* Single quotes.
* Correct pickHost documentation: wgMathMathMLUrl is not an array,
and is not used in this method, that's at a different level
of abstraction (via the constructor).
* White spacing.
* require_once is not a function.

Chrome in particular would end up with fairly small and inconsistent
background sizes when using background-size: contain;. This makes sense
according to the docs at
https://developer.mozilla.org/en-US/docs/Web/CSS/background-size, which
doesn't specify that the background actually has to fill the entire element.
background-size: 100% 100%; does force full-size scaling, which is what we
want. Verified to work as expected in Chrome 38 on Linux.

HTML tidy will strip empty spans, so don't use one for the fallback image. We
use a meta element instead, as that does not normally render at all & doesn't
have any default styling coming with it.

- Use span with a background-image instead of <img> for the fallback SVG so
that they don't load in Gecko.
- Make the image fallback a span inline-block so that it can have a dimension.

- Merge fallback-svg and fallback-png into one fallback-image class.
- Move the vertical centering of PNG to MathTexvc and ext.math.js.
- Remove "img" from ext.math.css to reduce CSS specificity and make

- Add a comment about the !important rules for centering in
display mode.
- Only load ext.math.scripts in MathML mode.

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
Javascript postprocessing.

hide the <math> tag in a way that still makes it accessible to

Use the cached function isInDatabase rather than readFromDatabase to
avoid unnecessary read operations on the database.
Currently, readFromDatabase is usually called only once during instance
livetime. But after I455b41c8b8d918f4c34f6c115194d227a8394e0a has bben
merged chances are that it's called twice.

Currently the error reporting in MathML mode is
misleading.
The old error message suggested that the MathML
produced is not well formed.
This change displays the actual error
message occurred during the conversion process.

In the default style MathML was rendered as inline and
not as display-style which was consistent to the current
behaviour of the PNG rendering.
By using the 'inline-TeX' rendering type the
display rendering is done independent of the rendering
of the surrounding block layout.

The PNG fallback for old IE versions worked
only if the PNG image was already stored in the
database.
This change enables the Specialpage that displays
the PNG images to create new PNG images and to
show them directly.
To test this commit you need an old IE version
(IE<9). If you don't have access you can use
an online service such as http://netrenderer.com.

Beginning from Mathoid 0.2.5 the specification
of a height and width attribute of the image will be required.
This patch gets those information from the SVG and copies
them to the img tag.

Currently, the PNG fallback is hidden in the MathML mode and the MathML & SVG
are respectively hidden and visible by default; the visibility of the
SVG/MathML output is only changed for Gecko. This does not work well for
IE < 9, which does not support SVG. This commit tries to improve the selection
of PNG, SVG or MathML according to the browser capatibility.
