If a limit is set, the window will use a small delay after each call to
display() to ensure that the current frame lasted long enough to match
the framerate limit. SFML will try to match the given limit as much as it
can, but since it internally usesnudsfml.system.sleep, whose precision
depends on the underlying OS, the results may be a little unprecise as
well (for example, you can get 65 FPS when requesting 60).
Limit the framerate to a maximum fixed frequency.
