Yunus Shaikh 5b49ab30b2 fix(agc): show the last frame's numbers in the performance overlay below 1 fps ...

Below 1 fps no one-second window holds two presents, so the overlay
showed FPS: 0.0, GPU: 0.0 MS and DRIVER: 0.0 MS, which is the common
case for titles that run slowly today. When the last second holds fewer
than two presents, FPS is now the last frame's rate, 1000 divided by its
time in ms, and GPU and DRIVER are that frame's growth of each total.
With two or more presents in the last second the numbers are the last
second's as before, so the two modes meet at 1 fps.

FPS below 1 is shown with two decimals: a frame every 2 s reads 0.50 and
one every 12 s reads 0.08. Times keep their format and their 9999 cap,
which USAGE.md now states for frames of 10 s or more. Nothing changes
while the overlay is hidden.
