Expanding on !2184 (merged), combining the new solution with high-accuracy sleep to reduce CPU usage with the old solution for accurate frame limiting. This gives identical results to the original solution while still giving a far lower CPU usage, which is beneficial for battery-powered systems like laptops.
Note that if any system somehow isn't able to reach under 100 microsecond accuracy, it will not busy-wait, although a system with such a low accuracy is currently not known to me (normal sleep accuracy is slightly above 50 microseconds, half of what the required accuracy is).
