        [GTK] Allow to build WebKitGtk+ with accelerated compositing
        https://bugs.webkit.org/show_bug.cgi?id=63404

        WebKitGtk+ needs to implement accelerated compositing for running CSS3 3D transforms
        and animation through GPU acceleration. We could implement GraphicsLayer using Clutter.

        * GNUmakefile.list.am:
        * platform/graphics/clutter/GraphicsLayerClutter.cpp: Added.
        (WebCore::GraphicsLayer::create): Not implemented yet.
        (WebCore::GraphicsLayerClutter::GraphicsLayerClutter):
        (WebCore::GraphicsLayerClutter::~GraphicsLayerClutter):
        (WebCore::GraphicsLayerClutter::setNeedsDisplay): Ditto.
        (WebCore::GraphicsLayerClutter::setNeedsDisplayInRect): Ditto.
        * platform/graphics/clutter/GraphicsLayerClutter.h: Added.
