title: Vertex Buffer Objects with SDL
body: <p>When using <em>SDL 1.2</em>, what do I need to include to be able to use OpenGL <em>Vertex Buffer Objects</em> (VBOs)?</p>
  
  <p>Currently, I only include <code>SDL.h, SDL_opengl.h, SDL_image.h</code></p>
  
  <p>And get the errors:</p>
  
  <p><code>glGenBuffersARB, glBindBufferARB, glBufferDataARB not declared in this scope</code></p>
