Make sure GLX_SGI_swap_control is set up correctly
glXSwapIntervalSGI only affects buffer swaps to the current GLX drawable. That means that calling it once in clutter_backend_glx_get_features isn't sufficent, so set it up in clutter_backend_glx_ensure_context to make sure it affects buffer swaps for the current drawable. http://bugzilla.openedhand.com/show_bug.cgi?id=2044 Signed-off-by: Emmanuele Bassi <ebassi@linux.intel.com>
