I need to come up with a way to pass a this object to a callback. I have two ideas.
1) Add a setThisObject(...) function that the callback needs to implement which should be called before handleEvent().
2) For callbacks that need a this object, pass it as the first argument, and offset the rest of the arguments by one.

I think I am leaning toward the second option.

generated?

What does this do? I have never seen this syntax before; it looks like it would make a base class constructor public, but I not know what that means. And also, it seems that since we inherit from ActiveDOMCallback publicly that it would already be public, so what is this for?

> Source/WebCore/Modules/geolocation/PositionCallback.h:40
>      virtual ~PositionCallback() { }

This is no longer needed now that we have a base class that already makes the detstructor virtual.

> Source/WebCore/Modules/geolocation/PositionCallback.h:41
>      virtual CallbackResult<void> handleEvent(Geoposition*) = 0;

Wish this was a reference instead of a pointer.

> Source/WebCore/Modules/geolocation/PositionErrorCallback.h:40
> +    using ActiveDOMCallback::ActiveDOMCallback;

>      virtual ~PositionErrorCallback() { }

Ditto. Same for all the other classes.

Yep. Will fix.

It adds all the constructors from ActiveDOMCallback to, in this case, PositionCallback. I found the section called "Inheriting constructors" in http://en.cppreference.com/w/cpp/language/using_declaration useful and interesting.

Good point, will remove.

The changes to MutationObserver / MutationCallback may have caused crashes (rdar://problem/34062022).
