        Added attachments() back to QTPixelBuffer, as they are necessary for CAImageQueue.

        WKCACFLayer contents()/setContents() now return/take a CFTypeRef instead of a CGImageRef, which allows
        a CAImageQueueRef to be set as a layer's contents.

        WKCAImageQueue is a simple C++ wrapper around the WebKitSystemInterface CAImageQueue functions.

        MediaPlayerPrivateQuickTimeVisualContext will now use a CAImageQueue to display movie frames if
        certain prerequisites are met (QuartzCore.dll and CoreVideo.dll version numbers must meet a certain
        threshold defined in MediaPlayerPrivateQuickTimeVisualContext.cpp).
