In order to allow GraphicsContext3D instances for WebGL and other APIs to share resources with the compositor's GraphicsContext3D, a WebGraphicsContext3D accessor needs to be added to WebView (WebKit/chromium/public/WebView.h). Initially this needs to be stubbed out; it can be fully implemented once other changes land.
