I'd be curious to know more about what your talking about. Do you have a link or something that could illustrate a C++ graphics library that uses boost style functors and other modern C++ techniques.
I was mentioning GPU-acceleration, but not in the context of "graphics library", but rather HPC code (specifically, signal- and image processing: Sourcery VSIPL++ (http://www.codesourcery.com/vsiplplusplus/) It uses expression templates heavily, and makes use of metaprogramming, for example to determine optimal implementations for operations, depending on data types, size, and alignment. An example of a domain where C++ can outperform the equivalent C API is where it can fuse expression evaluation, something that is much harder to do in C, where the compiler doesn't have the luxury of a strong type system, and thus can't quite as easily optimize away temporaries, or do compile-time dispatching.
