Taking full page screenshot with a Chrome extension

Question

Is there away to capture a screenshot of the full page, including what is below the fold, in a Chrome Extension?

The captureVisibleTab seems to be limited to what is

Answer 1

The standard approach seems to be to scroll around the page and capture screenshots at each part and then stick them all together. The official google screen capture plugin does this, but I found it to be buggy (at least on Mac OSX), so I wrote my own full page screen capture extension.
