Summary:
Follow the instructions in the TeX book for drawing \overlines. This uses the
same code as fractions to produce the bars. Also added the ability to cramp
styles (i.e. T -> T' and T' -> T').
Test Plan:
- Look at `\overline{x}`, `\overline{\dfrac{x}{y}+z}`, and
`\blue{\overline{x}}` to make sure they look good.
- Make sure the tests work
- Make sure the huxley tests look good (Not here yet :( )

Summary:
Make delimiter sizing work. This involved
- Adding the symbols for the remaining delimiters (like `\lfloor` and `\{`)
- Adding metrics for the size1, size2, size3, and size4 fonts
- Parsing delimiter sizing functions
- Using the big fonts when possible, otherwise building large copies of the
delimiters from scratch
Test Plan:
- See that
`\bigl\uparrow\Bigl\downarrow\biggl\updownarrow\Biggl\Uparrow
\Biggr\Downarrow\biggr\Updownarrow\bigm/\Bigm\backslash\biggm|
\Biggm|\big\lceil\Big\rceil\bigg\langle\Bigg\rangle\bigl(\Bigl)
\biggl[\Biggl]\Biggr\{\biggr\}\Bigr\lfloor\bigr\rfloor`
parses correctly (this contains all of the delimiters, and all of the sizing
modes)
- See that the huxley tests didn't change, and the new one looks good
- See the normal tests work

Huxley had some strange problems where screenshots kept getting messed up by
becoming different sizes than they were before. Node-huxley seems to have fixed
this problem, so we'll try using that instead.
Also, fix the sizing tests to the new syntax.
