cogl_framebuffer_add_fence creates a synchronisation fence, which will invoke a user-specified callback when the GPU has finished executing all commands provided to it up to that point in time. Support is currently provided for GL 3.x's GL_ARB_sync extension, and EGL's EGL_KHR_fence_sync (when used with OpenGL ES).
