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.

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.

- 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.

Tweak the position of spaces between function invocations and arguments
so that the expansion of mediawiki-specific functions (`\Rho`, etc) is
consistent with how spacing is added to normal function invocations.
This helps ensure that `texvc`/`texvccheck` is idempotent -- that is,
that it can parse what it emits, and render it without change.

The \overbrace, \overleftarrow, \overleftrightarrow, \overline,
\overrightarrow, \underbrace, \underline, \widehat, and \widetilde
commands take a single mandatory argument. Move \overbrace and
\underbrace to the fun_ar1nb list, since they handle trailing
subscripts and superscripts specially. Move the other functions to
the fun_ar1 list.

It is impossible to take the empty alternative for this production,
since any input which matches `litsq_aq` would instead match `lit_aq`
if the empty alternative is used. In addition, there is no action
clause for the empty alternative, so it wouldn't typecheck if the
empty alternative was possible.
This has no effect on the generated parser, but clarifies the grammar.
This commit matches a25078ff9d to
texvccheck.

The \AA and \textvisible space commands aren't valid in math mode.
Surround them with \mbox so that we switch to text mode before
emitting them.

- 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.

The style would set a margin both on the SVG & the surrounding img. We
transfer the styles to the image, so don't want them on the SVG. This avoids
applying margins twice, which led to clipping.

SVG.

- 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.
