WebGL is not really a "webby" API, so I don't think that it serves as a  
good reference for Web APIs. After all, it's a straight port of OpenGL,  
which in turn is a C API designed in the 90's. On the other hand (OT) it  
has its merits when it comes to architecture (e.g. its paradigms that  
support massively parallel implementations).
