Pros: - The code is simpler. - AA rendering is consistent between cached and uncached characters. - No long requires parsing color values to determine the alpha, which means that we no longer depend on #rrggbbaa color value support. Cons: - We're drawing without SPAA in some cases where we could be. Addresses this comment: https://github.com/xtermjs/xterm.js/pull/1327#discussion_r176109332
