        Implementing hardware accelerated compositing of layers for Chromium.
        Completely removed the existing software compositing path to replace
        it with code implemented using OpenGL.
        https://bugs.webkit.org/show_bug.cgi?id=38783

        Tests: Covered by existing compositing tests.
