Source and header is too big
The glxx.h file weighs in at 3MB, while the glxx.cpp file weighs in at 4. Indeed, the latter is so huge that Visual Assist patently refuses to parse it. Any project I use these files in slows to a crawl as Visual Assist uses up a massive quantity of memory to hold all of this stuff.
This makes using your library a non-starter, as it makes my IDE non-responsive.
