 // ScriptWrappableVisitor is able to trace through the objects to get all
 // wrappers. It is used during V8 garbage collection.  When this visitor is
 // set to the v8::Isolate as its embedder heap tracer, V8 will call it during
 // its garbage collection. At the beginning, it will call TracePrologue, then
 // repeatedly it will call AdvanceTracing, and at the end it will call
 // TraceEpilogue. Everytime V8 finds new wrappers, it will let the tracer
 // know using RegisterV8References.
