title: how to downgrade the openGL version up to 2.0 for testing purpose
body: <p>I am trying to create a software which is compatible with opengl version 2.0 and opengl version 3.2 (core profile). I am using glew to create my context. I have provided a compile time macro to specify the openGl version and I want to test scenerio when maximum openGL version supported is 2.0 and person selects 3.2. My computer supports openGL versions up to 4.5, So I am not able to test this scenario. I want to downgrade the openGL version supported to 2.0 so that I can test this scenario. One way is to use old glew version which supports maximum openGL version 2.0, so that glewIsSupported function will fail for versions > 2.0, but I dont want to change my glew library as this is not proper replication of scenario when the machine really just supports openGL 2.0. </p>
  
  <p>So my question is how can I downgrade my computer to support openGL versions up to 2.0? I want that glew check for 3.2 version support fails, So I can display an error message and stop.</p>
