 // A surface ID is composed of three parts: a namespace, a local ID, and a
 // nonce. The local part and nonce are allocated by the client using any scheme
 // that avoids duplicates and makes IDs unguessable respectively. The namespace
 // is allocated by the service and will be different for each client.
 //
 // The special id_namespace value 0 is equivalent to the namespace of the
 // client. This can be used to create, destroy and submit frames to
 // surfaces before learning the namespace and to reference other surfaces
 // owned by the same client. The actual id namespace must be used to pass
 // surface ids to other clients for them to reference.
 struct SurfaceId {
   // A service allocated ID identifying a client.
   uint32 id_namespace;
 
   // An identifier allocated by the client uniquely identifying a surface within
   // a client process.
   uint32 local_id;
 
   // A cryptographically secure random int chosen to make the SurfaceId
   // unguessable by other clients.
