// This class provides creation functions for the new resources with IPC
// backends that live in content/renderer/pepper.
//
// This is a bit confusing. The "old-style" resources live in
// webkit/plugins/ppapi 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 have
// an IPC reflector 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."
