This will allow 3D graphics context implementations to share resources like textures. Contexts with the shareResources flag set to true will be in the same resource namespace. For now, WebGL does not share resource, SharedGraphicsContext3D does and the context associated with the Chromium WebView does. There will be another patch downstream in Chromium to actually implement this.
