9c7f26b479 Fix argument font sizing in \fbox and \raisebox, fix font sizing in \TeX, \LaTeX, \KaTeX (#1787)
* Remove forced \normalsize in \raisebox

Fix #1786 (incorrect size of "E" in `\TeX`) by fixing `\raisebox` to
keep the current font size.  Previously, `\raisebox` was rendering its
second argument as if it were in `\normalsize\textrm{...}`; now,
the argument is just as if it were in `\textrm{...}`.

* Fix screenshots

* New "hbox" argument type to convert box-like arguments

* Review comments

19d9d83ad3 \color affects following \right, put array cells in their own groups (#1845)
* \color affects following \right

Fix #1844 by giving `leftright` nodes a `rightColor` attribute for how
to color the right bracket.  Now `\color` sets the macro
`\current@color` in the current environment (in particular, resetting
after `\right`), just like `color.sty` does in LaTeX.  This is used to
specially pass the current color into any following `\right` and then
into the `leftright` parse node.

* Support \hdashline

Support `\hdashline` from package `arydshln`. This PR acts as a complement to PR #1395.

Similarly to #1395, the dashed line is rendered as `border-bottom-style: dashed;`. That does not exactly match the `dashsegment` and `dashgap` lengths in `arydshln`, but it does render black lines with sharp edges.

This was an easier PR to write than #135 since KaTeX now has well established methods for pt-to-em conversions and nulldelimiter.

4801ab875a Support for top-level \newline and \\ in inline math (#1298)
* Support for top-level \newline and \\ in inline math

This was a little tricky because `\\` was defined as an endOfExpression.
Instead made `\\` a termination specific to an array environment.
Outside an array environment, buildHTML handles the `cr` object,
resulting in a `.newline` class.  Currently this turns into a
`display: block` (with appropriate vertical spacing) only in inline math,
matching LaTeX.
