[PATCH 0/1] MR7277: winewayland: Round the Wayland refresh rate to calculate the win32 display frequency.

[Alexandros Frantzis (＠afrantzis)]

Round the Wayland refresh rate instead of floor-ing it, to report a more
accurate win32 display frequency. This can slightly improve FPS values
in games that use the reported display frequency to drive their rendering.
