Mir doesn't bother to interpret the OpenGL version string. It goes
looking for the features it needs, properly. And the Mir demos almost
all work properly on i945 (except for bug 1275684)

Although if QtMir was trying to interpret the version string, I'm not
yet sure how that could cause this bug.

Bug description:
  Ubuntu Desktop Next fails to start. I just get a black screen and
  mouse pointer. So unity-system-compositor is working fine. Only the
  nested unity8 can't run:

  unity8.log:

  I've also verified mir_proving_server with mir_demo_client_* runs fine
  in another VT.
