Allow taking screenshot of a particular WebElement, instead of the whole web page

[wangyizhuo]

There is some work around to achieve this: http://stackoverflow.com/questions/13832322/how-to-capture-the-screenshot-of-only-a-specific-element-using-selenium-webdrive/23087000#23087000.

It would be nice if there's a simple API to achieve it.

The solutions on that page require using a library in the WebDriver local end to manipulate the screenshot. I am not sure if such a library exists for Dart, and if one does, I would prefer to not add a dependency on it.

That said, the W3C spec includes element level screenshotting, and when we start seeing it in WebDriver remote ends, it should be added to here.
