This blogpost is so silly. Agg is more like a meta library for constructing drawing APIs. Using it directly is quite painful. It even comes with Agg2D which is a simplified API. Another easy to use C++ drawing API is Qt's QPainter. It all comes down to how you design the API. C++ doesn't force you to come up with Agg if you really want something like QPainter. I expect the C++-translation of Cairo to be equally simple. We're talking about translating cairo_foo(ctx, params); to ctx.foo(params); and adding automatic memory management. API design is hard. If you have it in you to design a good C API, you could probably do the same in C++.
