        Fix LayoutTests/canvas/philip/tests/2d.composite.operation.highlight.html
        https://bugs.webkit.org/show_bug.cgi?id=48290

        "highlight" is not a valid globalComposite operation
        as per http://www.w3.org/TR/2011/WD-2dcontext-20110525/#compositing
        Therefore, removed the option from the source code.

        Tests: No new tests required.
        LayoutTests\canvas\philip\tests\2d.composite.operation.highlight.html can be used for testing.
