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 Firefox specific CSS changes require a special
setup of math fonts on the system. To avoid problems
OS dependent behavior, this browser specific modifications
are removed from the ext.math.css file.
There are a couple of places, where people can overwrite
their CSS rules individually.
For example from version 1.8 the plugin
cf. de1eec2f0d
Note that this change will make things worse for users
that chose the MathML rendering option and managed to
configure their font setup right.

* With the current settings for example the distance between
matrix rows is too large.

- load ext.math.css on mobile devices
- move the @font-face rules for the Latin Modern WOFF fonts into a separate
Desktop-only stylesheet.

- 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
style easier to override by user stylesheets.
- 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.

- add "Cambria" to workaround a bug on Firefox Windows.
- remove obsolete local fonts (MathJax and STIXGeneral).

- Mark the png and svg fallback as aria-hidden="true".
- For browsers without good enough MathML visual rendering,
hide the <math> tag in a way that still makes it accessible to
screen readers.

In some cases for example if the vagrant role
mobilefrontend is enabled the stylesheets are not
processed on mobile devices.
Without a default setting for the display attribute
all elements are displayed at the same time.

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.
Change-Id: Ie9b0fdb66c51fbf6be98df092ce4de29fbba6068
In the MathML mode, the SVG is always visible and for Gecko the MathML
output is visible too. This commit modifies ext.math.css to hide redundant
output for a given mathematical formula.

This sets the default font-family on <math> elements so that we try to use
OpenType MATH fonts that are likely to be installed or fallback to WOFF and
obsolete mathematical fonts.

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 adds a mechanism that allows
to fetch the HTML output.
In a followup commit the rendering function
is changed to return a boolean value rather
than the rendering result.
This will simplify the error handling and caching.

* Removes the MathJax heuristics that decides
if equations are centered or left-aligned.
* Introduces the attribute display to specify
if the math element is rendered in inline,
display, or inline-displaystyle.
* add css rules for display / inline math images
