* clutter/cogl/gl/cogl.c: (cogl_check_extension):
        Actually populate this func and remove the static alternate
        named one. Means GLX actually checks for available extensions.
        Other minor tidy ups.

        * clutter/glx/clutter-backend-glx.c:
        * clutter/glx/clutter-backend-glx.h:
        Add support for GLX_SGI_swap_control to do vblanking prefering
        over glXGetVideoSyncSGI. Should fix issues on Intel chips with
        very slow frame rates due to vblank problems.
        Thanks to  Michel Danzer for tips, see;
        http://bugs.freedesktop.org/show_bug.cgi?id=10542

        * test/test-actors.c:
        Change FPS to 60.
