* The main change is that if the swap interval is 0 then Mesa won't install a
* frame callback so that eglSwapBuffers can be executed as often as necessary.
* Instead it will do a sync request after the swap buffers. It will block for
* sync complete event in get_back_bo instead of the frame callback. The
* compositor is likely to send a release event while processing the new buffer
* attach and this makes sure we will receive that before deciding whether to
* allocate a new buffer.
