        [chromium] Use correct file name for dragging out images.
        https://bugs.webkit.org/show_bug.cgi?id=24887

        We try to guess an appropriate filename when dragging out images. In order, we try to use:
        - The filename suggested in the HTTP header.
        - The last path component of the source URL.
        - The alt text.
        This matches the behavior of the other WebKit ports.
