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.
