the "None" is here to end the list of attributes.
therefore the 2nd time we skip stencil buffer and multisample.
Intel drivers are sometimes really nice, and sometimes so buggy, but they are improving anyway, so don't hesitate to report your problems to the devs, it can help them !

Title:
  Wrong element set to None of array doubleBufferAttributes?

Status in Cairo-Dock : Core:
  Invalid

Bug description:
  cairo-dock states that I can't use OpenGL. Curios, since glxinfo says
  I have (Intel Ironlake). After some investigation I found a peace of
  code in cairo-dock-opengl.c (line 173) where
  doubleBufferAttributes[16] is set to None (old value is
  GLX_STENCIL_SIZE). After taking a look at this array, i think it must
  be index 17, since all even indexes are attributes and all odd are the
  expected values, aren't they? However, that would not solve my
  problems since GL_MULTISAMPLESAMPLES is expected to be 2 and glxinfo
  says that may graphics card don't support MS at all (if column MS
  num/ms ns of glxinfo's output is the correct one).
