(1) OK I don't care to argue about pixel format passing any more. If nesting needs it right now, then leave it. But I'd like to think we will eventually revisit it for a nicer solution.
(2) Nothing is bad about "using namespace" in most cpp files. In fact, it's very good to reduce the syntactic coupling and improve readability. There are some cases where it could be dangerous, but they're relatively rare.
