Why is this not a scoped_ptr?

[slavi, 2013/05/28 18:55:13]

I tried that first but the Resource struct needs to be copyable since it lives
in a STL container. A scoped_refptr would be nice but base::SharedMemory is not
ref counted.

     GLenum format;
     // TODO(skyostil): Use a separate sampler object for filter state.
     GLenum filter;
     ResourceType type;
   };
   typedef base::hash_map<ResourceId, Resource> ResourceMap;
   struct Child {
     Child();
     ~Child();
