Hash :3940a453 Message :Only call std::string constructor in gl::Error when necessary
std::string's constructor is very expensive in debug builds.
In some applications we have seen it use 10% of the CPU.
This change makes (e)gl::Error store a pointer to an std::string,
and only create a string when necessary.
