 190 //
 191 // The reasons we do it this way rather than extending the parallel
 192 // inheritance hierarchy we have for RenderWidgetHost/RenderViewHost
 193 // vs. RenderWidgetHostImpl/RenderViewHostImpl are:
 194 //
 195 // a) Extending the parallel class hierarchy further would require
 196 // more classes to use virtual inheritance.  This is a complexity that
 197 // is better to avoid, especially when it would be introduced in the
 198 // production code solely to facilitate testing code.
 199 //
 200 // b) While users outside of content only need to drive tests on a
 201 // RenderViewHost, content needs a test version of the full
 202 // RenderViewHostImpl so that it can test all methods on that concrete
 203 // class (e.g. overriding a method such as
 204 // RenderViewHostImpl::CreateRenderView).  This would have complicated
 205 // the dual class hierarchy even further.
 206 //
 207 // The reason we do it this way instead of using composition is

 209 // the split interface we avoid complexity within content and maintain
