It seems that it's avoidable to make callback cross-process when we
start to emitting events for GUI elements, without this feature our
implementation will be much more complicated. I will find a way to warn
about resources leak in browser.
Now it's forbidden for browser to store reference to objects (including
functions) in renderer, because when the renderer is destroyed, it's
extremely hard to clean all of corresponding objects in browser
correctly, which would cause very bad resources leak.
Now, when creating a remote object in renderer, the browser will
reference the corresponding object by storing it in a strong map. And
when the remote object in renderer is GCed, the corresponding object
will be dereferenced in browser.
Basic usage is:
remote = require 'remote'
Window = remote.require 'window'
w = new Window { width: 800, height: 600 }
Still need to do:
* Beter support for Array type.
* Remote objects should cheat devtools.
* Support cross-process callbacks.
