Sure. As do the concepts of shadows, reflection, refraction, etc, none 
of which have specialized constructs in OpenGL. You could add them which 
would increase complexity. An alternative is to get rid of special cases 
without losing any functionality, quite the opposite in fact. That was 
hard before shaders but much easier now.

A function!
