853e2a4fb7 Support more scripts in \text{} environments. (#1076)
* Support more scripts in \text{} environments.

This diff is a follow-up to PR #1060 which added support for Indic scripts.
In order to support Czech, Turkish and Hungarian text (at least) inside
\text{} environments, we need to recognize the Latin Extended A and B
Unicode blocks. The patch also adds support for Georgian, and enhances
support for Cyrillic by defining the entire Cyrillic unicode block instead
of defining symbols for a subset of Cyrillic letters as we did previously.

* Only return fontMetrics for supported Unicode scripts in text mode

The Unicode scripts listed in unicodeScripts.js are supported in text mode
but getCharacterMetrics() was returning fake metrics for them even in
math mode. This caused bad handling of \boldsymbol\imath

* use Mode from types.js

db1cccdeab Support \colorbox and \fcolorbox (#886)
* Support \colorbox and \\fcolorbox

These are functions from the `color` package. They accept text, not math. They also have padding similar to `\fbox`.

Because of the padding, the code in `buildHTML` is intermixed with the `\fbox` code. I have not (yet) created a new file in the functions folder. This way, the reviewer gets a cleaner diff.

* Fix lint error

092aa0c767 Add \smash, laps, spaces, and phantoms (#833)
* Add \smash, laps, spaces, and phantoms

1. Support `\smash`, including the optional argument from AMS.

2. Change `\llap` and `\rlap` so that they render in text style. Repeat: This *changes* KaTeX behavior.

3. Add `\mathllap` and `\mathrlap`. These will act as they do  in `mathtools` and as in previous KaTeX versions of `\llap` and `\rlap`.

4. Add `\mathclap` and `\clap`.

5. Add `\hphantom` and \vphantom`.

6. Add `\thinspace`, `\medspace`, `\thickspace`

7. Add `\hspace`.

This work will resolve issue #270 and parts of #50 and #164.

A. Perlis has written a [concise description](https://www.math.lsu.edu/~aperlis/publications/mathclap/perlis_mathclap_24Jun2003.pdf) of items 1 thru 5. Except for `\smash`'s optional argument. It's described in the [AMS User's Guide](http://texdoc.net/texmf-dist/doc/latex/amsmath/amsldoc.pdf).

Item 6 also comes from the AMS User's Guide.

* Fix test spec

* Exploit makeVList for smash

* update smash and phantom screenshots for chrome

* Pick up review comments

* Change test from \llap to \mathlap

\llap is fundamentally a text-mode function. We should not expect it to work correctly when given math-mode arguments. So test \mathllap instead.

* Correct \llap macro

A correction. The previous macro returned an error if given an argument with math-mode content, such as x^2.

The corrected macro will not return an error. It will instead return well rendered math, but letters are in `\mathrm` font.

* update \llap, \rlap, \clap macros to use \textrm

* update Lap screenshots

fafaf85f96 Fix MathML output for ' and large operators with limits (#788)
Summary: (@kevinbarabash)
This diff extracts MathML builder tests out into a separate file and
updates them to use jest snapshot testing.  It updates the output of
prime ' from using identifier nodes <mi> to operator nodes <mo>.  It
also updates large operators with limits to use munderover instead
of msupsub. I added an option to remove unnecessary mrows to buildGroup.
Right now it's only used for by groupTypes.supsub. I'll see if it can be used
elsewhere (everywhere?) in a follow up PR.

Test Plan:
- make test w/o errors
- verify mathml snapshots contain the desired markup

b866cd5224 Fix interaction between styles and sizes. (#719)
* Fix interaction between styles and sizes by implementing styles as sizes.

Rather than having both `textstyle` CSS classes and `size5` CSS classes
affect the font size (and step on each other), implement sizes more the
way TeX does: a command like `\displaystyle` changes the current size.

This is actually a simplification, since now only `size` affects the size.
Simplifies CSS and computation. Many screenshotter tests change; they
change to be more like TeX. For instance, `\sqrt` fixes some
discrepancies in size treatment.

Also:

Remove the `Options.withX()` methods in favor of `.havingX()`, which
might return the same `options`.

Remove `Style.cls()` and `Style.reset()`.

Remove `Options.reset()`. You should never modify an `Options`; they
should change only by the `havingX()` methods.

* Implement TeX sizing for scriptsize/scriptscriptsize.

At every size level. Also make the sizes match TeX to the last decimal.

* Review comments.

53e416e296 Revert "Remove trailing commas for IE 9 compatibility"
This reverts commit 4d2e46e7f6.

Having trailing commans makes diffs easier to read as it avoids modifying a
line just to add a trailing comma if there is another item to add at the end
of a list.  There are plans to switch to ES6 notation and to translate that
to ES5 as part of the build process.  Since that translation would remove
trailing commas, the IE9 problems that originally motivated the commit
should vanish soon.

4d2e46e7f6 Remove trailing commas for IE 9 compatibility
Summary: IE 9 doesn't like trailing commas. When we introduced eslint, we added
a bunch of trailing commas, which makes IE 9 sad.

Test Plan:
 - `make lint`
 - Visit http://localhost:7936/ using IE 9 on browserstack.
 - See that the math loads, and there are no errors in the F12 developer tools.

982e7be597 Calculate math classes from outputs, not inputs.
It's important to get spacing right that the domTree classes reflect
math atom types. So use those types exclusively, rather than
repeating the type mapping twice (once when building spans, once in
getTypeOfGroup).

* Remove getTypeOfGroup.
* Add getTypeOfDomTree (simpler).
* Adjust supsub type calculation.
* Adjust delimsizing internals.

c951df4269 Fix #4.
Post-process the list of atoms after they are created, changing
binary operators to ordinary atoms according to the TeXbook's
rules. This makes the `prev` argument redundant, so drop it.

This commit assumes that the math class (mop/mbin/mrel/etc.) comes
first in the `classes` list, if present. Add a TODO to change the
signature of `makeSpan/makeSymbol` to enforce this invariant.
