        Switch paintFillLayer and its progeny to use IntRect instead of four ints
        https://bugs.webkit.org/show_bug.cgi?id=60596

        Changing integers passed into paintFillLayer and other derivatives to IntRects
        and IntSizes that reflect their function.

        No new tests since this is just refactoring.
