-// WebWidgetTestProxy is used during LayoutTests and always instantiated, at
-// time of writing with Base=RenderWidget. It does not directly inherit from it
-// for layering purposes.
-// The intent of that class is to wrap RenderWidget for tests purposes in
-// order to reduce the amount of test specific code in the production code.
-// WebWidgetTestProxy is only doing the glue between RenderWidget and
-// WebWidgetTestProxyBase, that means that there is no logic living in this
-// class except deciding which base class should be called (could be both).
-//
-// Examples of usage:
-//  * when a fooClient has a mock implementation, WebWidgetTestProxy can
-//    override the fooClient() call and have WebWidgetTestProxyBase return the
-//    mock implementation.
-//  * when a value needs to be overridden by LayoutTests, WebWidgetTestProxy can
-//    override RenderViewImpl's getter and call a getter from
-//    WebWidgetTestProxyBase instead. In addition, WebWidgetTestProxyBase will
-//    have a public setter that could be called from the TestRunner.
