* fix: Correctly parse \ followed by whitespace
LaTeX parses `\` followed by whitespace including up to one newline
as equivalent to `\ `. (With multiple newlines, you get paragraph
breaks.)
Fix#2860.
* Improve comments
* Avoid second RegExp match in control words
* Document capturing groups

Support single characters having a catcode of 13 (active) or 12 (other),
and expand a macro defined for the character only if it's active.
This enables defining `~` as a macro, but avoiding expansion in URLs.
Fix#2924

* Fix parse timing by separating consume() into fetch() and consume()
Fix#1989, and generally cleanup parse timing (many fewer hoops to jump
through) by defining two methods on parser:
1. `consume()` marks the current token (`nextToken`) as "done", but
doesn't yet fetch the next token (setting `nextToken` to `null`).
2. `fetch()` fetches the next token if we don't already have one
(e.g., if last token was `consume()`d).
Before this change, `consume()` did both actions. By separating them,
and allowing the parser to live in a state for a while where `nextToken`
is `null`, it is far easier to change settings (in particular, math/text
mode and catcodes) before reading the next token, in a way that depends
on what we're parsing. For example, if an argument should be treated in
text mode, we can just set the mode in the argument parser, instead of
when the previous token was consumed. Similarly, if an argument should
be treated as a URL, we can just set the catcode of `%` in the URL
argument parser, and reset it after. We no longer have to take care to
reset things before calling `consume()`.
This change mostly involves changing `this.nextToken` to `this.fetch()`.
In a perfect world, we could use slightly fewer calls to `this.fetch()`,
but Flow doesn't realize that `this.nextToken` will be non-null after a
call to `this.fetch()`, so we need to use a few more calls to
`this.nextToken()` or a few more local `nextToken` variables.
* Remove now-unnecessary consumeMath
* Update Parser.js
* Re-enable \includegraphics now that we have trust setting
This reverts commit 5806b240b3.
* Include Khan Academy test logo in repo and use in test (fix#1892)
* Update screenshots
* Update documentation
* Add tests, cleanup existing tests
* Update snapshots
* Enable trust testing (trust=true by default)
* trust option to indicate whether input text is trusted
* Revamp into trust contexts beyond just command
* Document new trust function style
* Fix screenshot testing
* Use trust setting in \url and \href
* Check `isTrusted` in `\url` and `\href` (so now disabled by default)
* Automatically compute `protocol` from `url` in `isTrusted`, so it
doesn't need to be passed into every context.
* Document untrusted features in support list/table
* Existing tests trust by default
* remove allowedProtocols and fix flow errors
* remove 'allowedProtocols' from documentation
* add a comment about a flow error, rename urlToProtocol to protocolFromUrl
* add tests test that use function version of trust option
* default trust to false in MathML tests
* fix test title, remove 'trust: false' from test settings since it's the default
* \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.
* Add test
* Put each array cell in its own group/namespace
* Improve cell group isolation, add test and TODO
