+//
+// 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 classes."
