Similar to the other proxying surfaces (e.g. paginated) I made the observer an interal type and for the observer to masquerade as the observee for public interactions. So Rob is faced with the issue of how to tell if the surface he has is suitable for querying. One answer could be if the total elapsed time reported by the surface (or device) is 0, then it is not worth querying any further... -Chris -- Chris Wilson, Intel Open Source Technology Centre -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
