// (See pepper_in_process_router.h for more information.)

// This is a bit confusing. The "old-style" resources live in
// content/renderer/pepper and are created by the ResourceCreationImpl in that
// directory. The "new-style" IPC-only resources are in ppapi/proxy and are
// created by the RessourceCreationProxy in that directory.
//
// This class allows us to run new-style IPC-only resources in-process. We use
// the PepperInProcessRouter to run it in process. But then we have a problem
// with allocating the resources since src/webkit can't depend on IPC or see
// our IPC backend in content. This class overrides the normal in-process
// resource creation and adds in the resources that we implement in
// ppapi/proxy.
//
// When we convert all resources to use the new-style, we can just use the
// ResourceCreationProxy for all resources. This class is just glue to manage
// the temporary "two different cases."
