title: Create openGL context in linux console(Raspbian)
body: <p>I want to make a minimal visual display in console with openGL, but as far as my knowledge goes there has to be a window system involved(glut, glfw, sdl, etc..). </p>
  
  <p>I've seen <a href="https://github.com/huceke/omxplayer" rel="nofollow">omxplayer</a> build a graphic environment(I just assume it is openGL or something similar, so please correct me if I'm wrong) from console, in order to save some processing power, and make movies watchable in the PI.</p>
  
  <p>I'm just wondering how do they do it? Is there some literature in the topic? I'm mostly interested in solutions in C/C++, but any language with these capabilities would be great to know about!</p>
  
  <p>I scavenged through the source code, but couldn't really find a clue about this particular task. Any help or pointer would be appreciated!</p>
