Let's define these as empty classes in WebKit tree (without a virtual destructor
either), and have these be a subclass.  Similarly for TransferableResource and
TransferableResourceList.  Traits would also work on the subclass only.

+  gfx::Size size;
+  std::vector<cc::CCRenderPass*> render_passes;
+  cc::TransferableResourceList resources;
+};
+
+struct WebCompositorFrameAck {
+  cc::TransferableResourceList resources;
