-/**
- * This class contains logic for getting HTML contents out of the clipboard.
- *
- * We need to make a lot of ugly hacks to get the contents out of the clipboard since
- * the W3C Clipboard API is broken in all browsers that have it: Gecko/WebKit/Blink.
- * We might rewrite this the way those API:s stabilize. Browsers doesn't handle pasting
- * from applications like Word the same way as it does when pasting into a contentEditable area
- * so we need to do lots of extra work to try to get to this clipboard data.
- *
- * Current implementation steps:
- *  1. On keydown with paste keys Ctrl+V or Shift+Insert create
- *     a paste bin element and move focus to that element.
- *  2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
- *  3. Check if the paste was successful if true, process the HTML.
- *  (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
