title: `TypeError: perspectiveMatrix() got an unexpected keyword argument 'inverse'` in OpenGLContext callback
body: <p>I am starting to learn OpenGL and I tried to run the program in this <a href="http://pyopengl.sourceforge.net/context/tutorials/shader_1.xhtml" rel="nofollow">tutorial</a>. This is the code I have got together from that page. I had to lower the GLSL version in the shaders to get it to run at all on my laptop (they were 330).</p>

  <p>This is the error I am getting if I run the program. The error repeats if I move my mouse on top of the small window that appears, so the app is alive, but not really functional. The window shows what was behind it when the app started, so no real picture.</p>

  <p>I am a complete noob when it comes to OpenGL, so I really don't know where to start looking for a problem, as it is not even directly from my code, but by some callback. Do I have somehow incompatible packages?</p>
