Daniel van Vugt 56fc09151d clutter/frame-clock: Evenly space updates when presentation times are zero ... This is for the Nvidia-X11 driver where `last_presentation_time_us` is always zero. Other drivers should be unaffected. The existing `calculate_next_update_time_us` algorithm only provides a guarantee of not scheduling faster than the refresh rate in the presence of a valid `last_presentation_time_us`. When `last_presentation_time_us` is zero there is no solid foundation to guarantee we're not occasionally scheduling too early. So introduce one now. By introducing a hard guarantee that updates are never scheduled faster than the refresh rate, we avoid keeping Nvidia's triple (or quad?) buffer queue full. So this avoids the high latency and random stalls experienced on Nvidia.
