-// Wraps WebContents and all of its supporting objects in order to control

-//
-// WARNING: Not every place where HTML can run has a TabContentsWrapper. This
-// class is *only* used in a visible, actual, tab inside a browser. Examples of
-// things that do not have tab wrappers include:
-// - Extension background pages and popup bubbles
-// - HTML notification bubbles
-// - Screensavers on Chrome OS
-// - Other random places we decide to display HTML over time
-//
-// Consider carefully whether your feature is something that makes sense only
-// when a tab is displayed, or could make sense in other cases we use HTML. It
-// may makes sense to push down into WebContents and make configurable, or at
-// least to make easy for other WebContents hosts to include and support.
-//
-// TODO(avi): Eventually, this class will become TabContents as far as
-// the browser front-end is concerned.
