Ed Sanders 407bfc4f3b Limit overflow-x rule to block elements
The overflow-x rule has no effect on inline elements
anyway, as documented in T134281, and it confuses
logic in VE for computing highlights.

Moritz Schubotz c877e564fc Add scrollbars to displaystyle formulae
Add mwe-math-element class attribute to the outermost element
holding mathematical expressions. Add a css rule that adds a
scrollbar to the element in case it's a div, which is the case
for displaystyle formulae.

Note, there will be no scroll bar if long formulae are not
explicitly marked up das displaystyle formulae.ƒ

Physikerwelt 797c8ddfc9 Revert "Add class mwe-math-element to math elements"
This reverts commit e674d7e73b.
That commit does not help to solve T134281.
It adds a CSS class name which is configurable
by a global variable to various math elements, which is confusing.

This is the fix for the bug that makes the whole page scroll when long 
equations are present in the wiki article.

Frédéric Wang be7be3becb Remove woff fonts
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).

Frédéric Wang d808880450 Remove some obsolete CSS rules that are no longer needed in Firefox ESR 45:
- Use the non-math font Cambria first (fixed in https://bugzilla.mozilla.org/show_bug.cgi?id=598900).
- Set line-height to normal (fixed in https://bugzilla.mozilla.org/show_bug.cgi?id=1187673).

Moritz Schubotz f071dbcf80 Remove Firefox specific CSS styles
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.

Frédéric Wang d4e928a486 SVG images should not be loaded when MathML is used
- 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.

- 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.

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.

  screen readers.

Frédéric Wang 382454a979 Update modules/ext.math.css
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.

physikerwelt c390f6479a Add getHtmlOutput method
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.
