        [chromium] Adding support for reflections to the accelerated
        compositing path.
        https://bugs.webkit.org/show_bug.cgi?id=53179

        All layout tests in compositing/reflections generate correct
        results with the exception of:
        1. nested-reflection-anchor-point.html : There appears to be
           some issue with the layer transform math that I haven't been
           able to track down yet.
        2. reflection-opacity.html : The current implementation applies
           opacity before doing the reflection which makes this test
           produce incorrect results.  This will affect reflected layers
           with opacity that overlap their original layer.  FIXME comment
           added in the code.

        Tests: Covered by existing layout tests in compositing/reflections.
               Please see above for exceptions.
