// This file is used to define IPC::ParamTraits<> specializations for a number
// of types so that they can be serialized over IPC.  IPC::ParamTraits<>
// specializations for basic types (like int and std::string) and types in the
// 'base' project can be found in ipc/ipc_message_utils.h.  This file contains
// specializations for types that are used by the content code, and which need
// manual serialization code.  This is usually because they're not structs with
// public members, or because the same type is being used in multiple
// *_messages.h headers.
