Subject: [PATCH] backend: Clean up renderer after clutter backendm
commit c4a73e795020722eda3e2bec0c16d96f9f37333b added
code to cleanup the renderer when the meta backend is
disposed. Unfortunately, this introduced a crash when
the window manager is replaced.
This is because cleaning up the renderer involves talking
to the X server over a display connection that's closed
two lines higher as part of the clutter_backend_destroy
call.
This commit fixes the crash by swapping their order.
