        [Chromium] Make accelerated 2d canvas enabled by default with skia
        https://bugs.webkit.org/show_bug.cgi?id=59929

        No new tests. Covered by existing layout tests

        * html/canvas/CanvasRenderingContext2D.cpp:
        (WebCore::CanvasRenderingContext2D::CanvasRenderingContext2D):
        Initialized for accelerated canvas if either the accelerated2dCanvas
        or the legacyAccelerated2dCanvas flags are enabled
        * page/Page.cpp:
        (WebCore::Page::sharedGraphicsContext3D):
        This is where the code goes to implement the functionality for the
        legacy vs current acceleration paths for the 2D canvas. Currently,
        this is a no-op, and always select the legacy path.  This is temporary
        until we are ready to sort the GPU layout tests (rebasline vs. bug)
        * page/Settings.cpp:  Added new flage for legacyAccelerated2dCanvas
        (WebCore::Settings::Settings):
        (WebCore::Settings::setLegacyAccelerated2dCanvasEnabled):
        * page/Settings.h:
        (WebCore::Settings::legacyAccelerated2dCanvasEnabled):
