Merge branch 'master' of git+ssh://agd5f@git.freedesktop.org/git/mesa/mesa into r6xx-rewrite

This builds, but I get an assertion in radeonGetLock() due to
the drawable being null.

- * This is a port of the infamous "gears" demo to straight GLX (i.e. no GLUT)

+ * Version of glxgears that creates/destroys the rendering context for each

+ * Good for finding memory leaks, etc.
  *
  * Command line options:
  *    -info      print GL implementation information
- *    -stereo    use stereo enabled GLX visual
