            <rdar://problem/6988966> Hardware layers do not show up in page snapshots

            * WebView/WebHTMLViewPrivate.h:
            * WebView/WebHTMLView.mm:
            (-[WebHTMLView _compositingLayersHostingView]):
            Add a private method that returns the NSView used to host compositing layers.

            * platform/graphics/mac/Canvas3DLayer.h:
            * platform/graphics/mac/Canvas3DLayer.mm:
            (-[Canvas3DLayer copyImageSnapshotWithColorSpace:]):
            Add a method that gets called when snapshotting Canvas3DLayers for page snapshots,
            that allows the layer to return a CGImageRef of its contents. 

Unclear if it's still used.
