- Also fixes actually using Roboto-Mono, xterm.js now only accepts
fontFamily customization via the JS api. (uses `<canvas`).
- There is an issue (https://github.com/xtermjs/xterm.js/issues/1170)
if linux has to fall back to 'monospace' where things fail to render
correctly, so provide a couple of common options so this rarely
happens.
- If we distribute robo-mono in the webpack bundle that might also work.
