72362ecf88 Correct spacing next to symbols when styles switch.
Two nodes were sharing a list of classes, which led to the style
change applying multiple times. Fix that.

6bb62b11b4 Support \mathop, \mathrel, \mathbin, \mathpunct, etc. class commands.
These commands set their arguments in a given TeX math class. Use
the existing "op" type for \mathop (to support \limits); introduce
a new "mclass" type for the other classes.

Fixes #482. Tests borrowed from #485 (cbreeden).

dc79b91dbf Mark delimiters with the proper class (mopen or mclose).

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.

9d3cdf694c Fix spacing between groups to match TeX spacing (#567)
* Internal: Pass full `options` objects to makeSpan/makeSymbol.

Not just the current color. This will facilitate applying options
to built nodes in a standardized way, rather than changing all
callsites.

* Add style switching test: text and scriptstyle in the same group.

* Apply style-specific spacing using different CSS coding.

Specifically, infer style from a class on the *current* element,
rather than the parent element. Use "mtight" class to denote elements
with tight spacing (scriptstyle or scriptscriptstyle). Apply that
class automatically based on options.

* Fix #533, #534, #541.

- #534: Implement getTypeOfGroup for font groups.
- #533, #541: Improve the ways spaces are applied to lists. Since
  CSS adjacency implements mathematical spacing, it's incorrect to
  introduce "convenience spans" for spaces and display changes into
  the generated HTML -- those spans break adjacency. Apply display
  changes directly, and shift space spans into adjacent atoms.

Requires updates to two screenshotter tests, LimitControls and
SupSubLeftAlignReset. The new results for these tests are closer
to TeX output than the old results.

Also requires updates to Jasmine tests, since those assumed output
structures that have changed.

* Fix #136: Size commands generate fragments, not spans.

This is so the size commands don't hide the types of their enclosed
atoms. Addresses #136.

This slightly changes the vertical position of the Sizing test. Not
sure the vertical position matters, so change the test.

d5025c61e8 Fix texcmp issues related to bit depth and kerning (#549)
* Ensure bit depth 8
* Print affected file if PNG failed to read (e.g. due to wrong bit depth)

ec62ec39d8 Add support for Latin-1, Cyrillic, and CJK characters inside \text{} (#508)
Summary:
This diff provides support for Latin-1, Cyrillic, and CJK characters
inside \text{} groups.  For Latin-1 and Cyrillic characters we use
glyph metrics from a glyph from Basic Latin that has roughly the same
bounding box.  We use the metrics for a capital 'M' to approximate the
full-width CJK characters.  Half-width characters are not supported yet.

Test Plan:
- make test
- make screenshots

4a9c2acbf7 Add some more symbols (#502)
This adds support for the following input sequences:

    -- --- ` ' `` '' \degree \pounds \maltese

resulting in – — ‘ ’ “ ” ° £ ✠ symbols already present in our fonts.

As part of this modification, the recognition of multiple dashes was moved
from the lexer to the parser.
This is neccessary since in math mode a sequence of hyphens is just a
sequence of minus signs.  Just like a pair of apostrophes in math mode is a
double prime not a right double quotation mark.
To make this easier, parseGroup and parseOptionalGroup have been merged.

3083efba66 Add support for \kern
Summary:
This only supports em and ex units and doesn't handle vertical layouts.
Negative kerning works.

Test Plan:
- make test
- make screenshots (verify that d is slightly overlapping c in the screenshots)

8201501d77 Introduce an aligned environment
This is almost like the align* environment, but it starts out in math mode,
so we don't have to worry about the fact that we have no real surrounding
text mode in KaTeX.  This is the first step towards align* and align.

71881e3d36 Make texcmp work again, including KaTeX logo
Since all the math font test cases use the KaTeX logo, we need that.
I started with the definition of the logo from katex.less, but tweaked that
until it gave a good visual match, in particular a very similar logo width,
no matter the actual numbers.

With that logo, most tests can be compiled again, with the exception of the
one containing illegal functions to test visual error reporting.
That one needs to be explicitely disabled.

d6cec8a861 Rename breakOnUnsupportedCmds to throwOnError.
Also, the MathBb-chrome test changed, to what I believe is the correct
result? Not sure why it looked wrong before.

Test plan:
 - `make test`
 - take screenshots, see nothing changed.

3a8adbf595 Add | column separators to arrays.
This adds the ability to add `|` to a column description and have
vertical separators be added. I added types to the column descriptions
and added some logic to handle the separators when building the vertical
lists of the array.

Test plan:
 - See the Arrays screenshot looks good.
 - `make test`

fd2d58fd80 Adds math commands, HTML rendering, and screenshotter tests.
This is part 2 of 3.  Part 1 added new fonts metrics.  Part 2 will add MathML support and unit tests.

fb403fa9eb Switch Screenshotter data from JSON to YAML
Escaping TeX in JSON as query strings is a pain: you have to double all the
\\, you have to escape the & and the #, you can't easily include line breaks
for readability, and so on.  YAML solves most of these problems for most of
the situations.  Now each test case can be structured, while simple test
cases only consist of a line of verbatim TeX code, with no escaping.

The most troublesome items remaining are lines starting in { since in YAML
these would denote inline mapping types. We use block notation for these.
