        This test verifies that a compositor-painted blur filter does not add filter outsets to
        the composited layer bounds.

        Note: Some platforms' compositors may not be capable of computing their own filter outsets
        yet, so they will need different expectations that include filter outsets in the composited
        layer bounds.
