title: glxinfo vs. glewinfo interpretation
body: <p>I have difficulties interpreting glxinfo and glewinfo.</p>
  
  <p>glxinfo gives me this:</p>
  
  <pre><code>OpenGL version string: 3.0 Mesa 9.2.2
  OpenGL shading language version string: 1.30
  </code></pre>
  
  <p>whereas glewinfo goes up to version 4.0:</p>
  
  <pre><code>GL_VERSION_4_0:                                                OK 
  ---------------
    glBlendEquationSeparatei:                                    OK
    glBlendEquationi:                                            OK
    glBlendFuncSeparatei:                                        OK
    glBlendFunci:                                                OK
    glMinSampleShading:                                          OK
  </code></pre>
  
  <p>I know that I cannot use GLSL newer than 1.30, but I'm wondering, is that a driver issue?</p>
  
  <p>My GPU is </p>
  
  <pre><code> VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
  </code></pre>
  
  <p>I'm using Arch Linux and SDL, and have Mesa 9.2 and Mesa-libgl 9.2.2 installed.</p>
