We don't go through the delusion that each a person of these policies might be efficiently applied to each and every code base. Upgrading aged programs is difficult.
This draw2() passes the exact same total of knowledge to draw(), but can make The point that it can be speculated to be A selection of Circles express. See ???.
One particular consequence of that is definitely that some policies might be supported only by heuristics, in lieu of exact and mechanically verifiable checks.
