Headless mode

Headless mode allows running Chromium in a headless/server environment. Expected use cases include loading web pages, extracting metadata (e.g., the DOM) and generating bitmaps from page contents -- using all the modern web platform features provided by Chromium and Blink. To use headless, start Chrome with a command line flag: $ chrome --headless --remote-debugging-port=9222 https://chromium.org
