title: Why is the Graphics Pipeline so highly specialized? (OpenGL)
body: <p>The OpenGL Graphics Pipeline is changing every year. So the programmable Pipelines are growing. At the end, as an opengl Programmer we create many little programms (Vertex, Fragment, Geometry, Tessellation, ..)</p>
  
  <p>Why is there such a high specialization between the stages? Are they all running on a different part of the hardware? Why not just writing one code-block to describe what should be come out at the end instead of juggling between the stages?</p>
