Allow theming with arbitrary CSS color strings #1346

Really nice PR, this is addressing one of the bigger areas of concern, thanks! If I'm reading the code correctly, passing alpha values like There's also one test failling: |

I've wanted this gone for a long time 😛

This looks great, I haven't tested the code but if everything works fine and the tests pass then I'm 👍 |

I've fixed the test, and amended the commit!
This parses alpha channels.
Selections work as expected. They're partially transparent. |

It might make sense to pull in node-canvas (which JSDom integrates with) as a dev dependency if we want to test more rendering-related codepaths, but this works for now.

I want to improve the testing situation, I was thinking about puppeteer but I'm not sure if that's the right tool for the job thinking about it some more. #1247
This mostly worked before, but clearColor made the assumption that the colors were always in #RRBBGG format. See the discussion here: xtermjs#1327 (comment) This changes the internal representation of a color so that we hold onto into an object containing the original css string along with an RGBA value encoded as a 32-bit uint. clearColor can then use that RGBA representation. Additionally, this deduplicates some code between ColorManager and Terminal. Terminal was generating the 256 ansi colors the same way ColorManager was, so this just makes Terminal use the same constant.
Fixes xterm/xterm.js#1357.

I merged bgw#2 (Block transparent colors without allowTransparency) into this PR, and I'm not aware of any outstanding issues, so I think this is ready to be merged. I'll do the node-canvas stuff as a separate PR once this stuff lands. |

Thanks @bgw 👍 |

and so does the 24-bit color approximation:
The static char atlas looks sane, so
clearColoris working:We can change the theme using arbitrary css strings:
And
clearColorstill works properly, but now using a pink background:
