Bug 33523 – [V8] Support injection of inspector scripts into the inspected context

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Yury Semikhatsky]

Part of Web Inspector is implemented in JavaScript and needs direct access to
the inspected JS objects. To facilitate this there should be a way to compile
the inspector utilities(called injected script) in the global scope of the
inspected ScriptState and somehow store a reference to it(we need to keep the
reference since the injected script keeps some state related to the inspected
DOM, CSS styles and JS objects).

InspectorBackend?

inspector backend wrapper ?

So this script source should evaluate into function? Could you on comment why it is so?

Otherwise looks good.
