Research direction

Start with the Node.js addon examples and the ObjectWrap, Local, and Local API documentation named in the issue. Done means documenting a supported way to create an ObjectWrap-backed value and pass it to the persistent JavaScript callback without constructor round-tripping.

Written by the indexing model from the issue text.

Description

I cannot find any information on how to create an ObjectWrap and pass it as an argument to a Local. I have a persistent callback registered and need to call it with a new instance of an ObjectWrap. I could do this by calling the (JS) constructor and pass it (JS) arguments which returns a new instance, but I want to avoid this round tripping.

Basically: how to create an ObjectWrap and get a Local out of it so that I can pass it as an argument to a JS function?
