Add an accessibility delegate interface to Windows solution

• Component: Accessibility
• Status: RESOLVED FIXED

[Roger Fong]

So client's can do stuff when Frame loads start and finish.
Some accessibility programs like WE require that certain notifications be sent from OUTSIDE of webkit when a frame is being loaded.
This API allows this.

Looks good -- but we're missing the AccessibilityDelegate.idl file!

I usually return E_POINTER

Doh.

 Hmm what's the difference? I was just copying what the other delegate getters in the file were returning.

E_POINTER is returned when the caller doesn't supply a valid pointer to the routine.

You might consider fixing the parameter name warnings from the style bot. I'd also get rid of the STDMETHODCALLTYPE declarations in the CPP file (leave them in the header file).

> Source/WebKit/win/WebView.cpp:2874
> +HRESULT STDMETHODCALLTYPE WebView::setAccessibilityDelegate(

You don't need STDMETHODCALLTYPE in the implementation -- only in the header.

> Source/WebKit/win/WebView.cpp:2881
> +HRESULT STDMETHODCALLTYPE WebView::accessibilityDelegate(

You can remove STDMETHODCALLTYPE
