        Fix for bug 22119, clicks in the scrollbars of transformed content don't work.  Add new
        conversion methods for going across parent/child widget boundaries that can be implemented
        by the FrameView and ScrollbarClient to be transform-aware.

        Test cases added in platform/mac/fast/forms and platform/mac/fast/overflow.
