This is at least a first step towards fixing xtermjs#1247. This adds some complexity to the initial setup, since canvas needs to be built from source. This won't be true once canvas 2.x is stabilized, because that version downloads (Automattic/node-canvas#992). JSDom doesn't support 2.x, and doesn't until a stable release is cut. We could use [canvas-prebuilt](https://github.com/node-gfx/node-canvas-prebuilt), which JSDom does appear to support. However, I'm not sure if that would cause pain for people with 32-bit operating systems (see the compatibility table on that page). I'm not sure if this travis configuration will work; I'll iterate on it in the PR if it fails. I removed a bunch of hacks that were added in xtermjs#690, since they don't look necessary anymore (the sleep module is gone).

@Tyriar, I'm doing this as a PR into my own color parsing branch instead of adding it to that existing PR, because this contains some significant tradeoffs. It looks like I can't test the travis stuff because this PR isn't against xtermjs/xterm.js. I'll open a new PR against master once xtermjs#1346 lands. |
