 193 //
 194 // The reasons we do it this way rather than extending the parallel
 195 // inheritance hierarchy we have for RenderWidgetHost/RenderViewHost
 196 // vs. RenderWidgetHostImpl/RenderViewHostImpl are:
 197 //
 198 // a) Extending the parallel class hierarchy further would require
 199 // more classes to use virtual inheritance.  This is a complexity that
 200 // is better to avoid, especially when it would be introduced in the
 201 // production code solely to facilitate testing code.
 202 //
 203 // b) While users outside of content only need to drive tests on a
 204 // RenderViewHost, content needs a test version of the full
 205 // RenderViewHostImpl so that it can test all methods on that concrete
 206 // class (e.g. overriding a method such as
 207 // RenderViewHostImpl::CreateRenderView).  This would have complicated
 208 // the dual class hierarchy even further.
 209 //
 210 // The reason we do it this way instead of using composition is
